Reliable modern bathtubs for sale OEM for family decoration

Hotel name: Kah-Nee-Ta resortAddress: 6823 Hwy 8, Warm Springs, OR 97761, AmericaOpening: 18tth, July, 2024 Let me tell you about a project we’re particularly proud of—our custom bathtub design for the Kah-Nee-Ta Resort in the USA. Located at 6823 Hwy 8, Warm Springs, OR 97761, this resort opened its doors on July 18th, 2024, and we were thrilled to be part of it. The client had some pretty specific needs, and we were more than up for the challenge. What Makes This Bathtub Special?The folks at Kah-Nee-Ta wanted a wide-rimmed bathtub that could comfortably fit 4-6 people. Sounds simple, right? But we took that concept and ran with it. We designed an internal round seat that’s not just comfy but also practical. We even added a unique five-pointed star shape in the middle to make sure everyone has plenty of room to stretch out their feet. It’s the kind of design that not only works but also looks incredible—definitely a head-turner. We didn’t stop there. We also put a lot of thought into the seat and backrest heights. After all, what’s the point of a fancy bathtub if it’s not comfortable? We used average sitting heights to make sure the seat is just right, so guests can relax in style. The Challenges We Faced and NailedNow, this wasn’t an easy project. For starters, this was the first time we tackled a double-layer bathtub with a whopping 1880mm diameter. It took a lot of manpower and some serious skill to combine the internal and external structures seamlessly. Another tricky part was the drain. With all that water, the pressure was intense, and regular drains just couldn’t handle it. So, we designed a custom drain that’s strong enough to do the job. Oh, and did I mention the bathtub weighs 470KG? Yeah, it’s heavy. We had to custom-build the packaging, complete with a steel-reinforced bottom tray, to make sure it arrives safely at the resort. What This Says About UsThis project really shows what we’re all about. We don’t just meet our clients’ needs—we exceed them. From designing the product to making sure it’s safe to transport and easy to use, we’ve got everything covered. When you work with us, you’re getting a full-service experience that leaves nothing to chance.Who’s Gonna Love This?The Kah-Nee-Ta Resort project is a perfect example of what we can do for Spa Hotels, customized product seekers, and luxury hotels. If you’re looking for something unique that stands out and delivers on both form and function, we’re your go-to team.So, if you need a custom bathtub (or anything else), give us a shout. We’ll make sure you get something that not only fits your needs but also blows your expectations out of the water.

Are the overwhelming choices of countertop material making you restless? Consider the refreshing option of acrylic solid surfaces. Whether you are building furniture, sanitary products, wall tiles, or signages, acrylic solid surfaces will find a place in your raw material. It's a durable, budget-friendly, and aesthetically pleasing material that comes in sheets to provide perfect, seamless builds that speak modernity.The wide variety in colors, compositions, thicknesses, and lengths can compel someone to select an acrylic solid surface for their builds. However, purchasing one is a long-term decision. Considering the severity of the decision, analyzing all types, and understanding what is best for your workplace, home, or healthcare facility can lead to a satisfactory experience. So, let's start exploring!Acrylic Solid Surface Brief IntroductionAcrylic solid surface is an evolution of DuPont's first-ever solid surface material, Corian. It was introduced in 1967 and marketed as suitable for kitchen and bathroom applications. However, product applications grew with time, and now, acrylic is practical in everything from countertops to medical equipment.The chemical composition can vary depending on the type of acrylic solid surface. The critical component remains resin synthesized with acrylate or methacrylate as the main monomer. Dr. Otto Rohm developed this thermoplastic or thermosetting plastic in 1901. DuPont later fused the resin with material from bauxite ore to form a solid surface. There are different types of acrylic solid surfaces:● Texture Pattern Solid Surface● Modified Acrylic Solid Surface● 100% Pure Acrylic Solid Surface● Translucent Solid SurfaceWhy Use an Acrylic Solid Surface?There are many reasons to include acrylic solid surfaces in your next renovation or build project. Acrylic solid surfaces provide durability and thermoforming capability, allowing the development of unique shapes. The construction looks flawless and compatible with modern and contemporary design styles. Here are the top reasons to choose an acrylic solid surface:● Non-Porous Surface: Goodbye to Stains, Bacteria, and MoldAcrylic solid surfaces are resistant to stains and marks caused by liquid spills. Their non-porous surface does not allow liquid to penetrate and cause permanent damage. Only a tiny amount of soap mixed with water keeps the surface clean and shining like the day you got it installed. Owing to its non-porous surface, bacteria and mold cannot grow, and cleaning becomes convenient.● Seamless Construction: Premium Flawless LooksChemical bonds and adhesives are convenient for solid acrylic surfaces. They join easily to form a seamless connection. The resin, being the main component, allows for a continuous surface when joined by a technician. Using chemical bonds can cause two acrylic sheets to form a bond at the molecular level, which then undergoes polishing and finishing to create a unified look.● Bendable (Thermoforming): Unique Design and Reduced WasteA skilled installer can bend an acrylic solid surface sheet into unique shapes by applying decent heat. Cutting and joining acrylic solid surface sheets at the edges is unnecessary. The result of its thermoforming capability is reduced waste with an excellent finish. Skilled fabricators can bend solid acrylic surfaces into unique shapes and designs that are otherwise impossible in stone.● Light Weight: Convenient Transport and Swift InstallationAcrylic material has a density of around 1500kg/m3 (94lb/ft3). A marble or granite has a density of around 3200kg/m3 (200lb/ft3). If we take a 3-meter long, 1-meter wide, and 12mm thick solid surface of both materials, then acrylic would weigh 63kg, and marble would weigh 115kg. Acrylic solid surfaces are more accessible to carry and transport. Installation of acrylic material is convenient and requires lighter support.● Ease of Maintenance: Sand, Buff, and Polish Away ScratchesDid you accidentally drop something sharp on your brand-new acrylic solid surface? It's not a problem. There is no need to apply an expensive treatment layer or coating. All you need is a fresh buff, and you are good to go. There is no need for any chemical or time-consuming treatments.● Enhanced Safety: Does Not Shatter or BreakUnlike glass or marble, the edges of acrylic solid surfaces do not break away under impact. Unlike other materials, it is challenging and withstands loads. However, shattered glass can be a safety hazard for homes with children.● Heat Resistance: Use Near Heat SourcesAcrylic solid surfaces offer moderate heat resistance compared to lamination, polyester, and blend. The glass transition temp acrylic is 252 °F (122 °C), necessitating trivets. It can handle decent heat, allowing users to install it in locations near heat sources.Acrylic vs. Other Solid SurfaceWe must explore all our options to comprehend the need for acrylic solid surfaces. It will shed light on why they are superior for widespread use. There are mainly four types of solid surfaces:◀ Granite or Marble: Scratch Resistant but BrittleIt is one of the most ancient materials with historical significance in our modern lifestyle. Although granite and marble have different properties, both are naturally occurring rocks on Earth. Each undergoes a different process to reach its final composition. Granite is tough and more durable than marble. However, marble has aesthetics that are otherwise impossible in granite. Granite is heat resistant and does not easily etch like marble.Do acidic liquids like lemon juice, coffee, soda, and tomato sauce instantly damage your solid surface? You may have a granite or marble countertop. Both are porous materials that can instantly damage in an acidic environment. The material is brittle and instantly breaks or cracks on impact. Compared to acrylic solid surfaces, thermoforming is not an option with natural stones. However, they perform better against scratches, heat, and UV light.◀ Polyester: Affordable but Susceptible to ScratchesPolyester looks similar to a solid acrylic surface. However, it has critical characteristics that make it different in performance. The polyester resin, fillers, and pigments form the polyester solid surface. Polyester is less expensive, which makes it an attractive option for low-budget builds.However, polyester is susceptible to scratches and chipping compared to acrylic solid surfaces. Thermoforming is also not an option with polyester, as it can damage easily against high heat. The seams of the acrylic solid surface are not visible, whereas the polyester seams are visible.◀ Blend: Combine Polyester and AcrylicAs a user, if you want acrylic scratch, heat, and chemical resistance while having the color option and budget-friendliness of polyester, then a blend solid surface should be your choice. It combines the positive aspects of both materials. Merging the affordability of polyester with the strength of acrylic material makes it an excellent option for mid-range builds.◀ Quartz: Manmade with Natural StonesAnother name for Quartz is “Engineered Stone.” The final form of quartz does not occur naturally. The naturally occurring Quartz crystals are extracted from the Earth and crushed. Resins, pigments, and binders are mixed with 90-95% quartz crystals to form a solid surface. It provides better resistance to chipping, scratches, and heat than acrylic. Compared to an acrylic solid surface, engineered stone has some porosity, requiring occasional sealing to prevent stains.◀ Laminate: Multi-Layer but VulnerableIf you are looking for extreme affordability, laminate is the way to go. Manufacturers create them by using layers of multiple materials. It has a particle board that is protected using plastic kraft paper at the core. On top of the kraft paper is the decorative layer that has the design the user requires. Finally, a transparent melamine layer protects the design layer. Laminates are great if you aim to renovate now and then. However, they lack longevity and durability in comparison to acrylic solid surfaces.Here is a quick comparison in tabular form:FeatureAcrylicGranite/MarblePolyesterBlendQuartzLaminateMaterialMan-made polymerNatural stoneMan-made resinAcrylic & Polyester mixMan-made (quartz + resin)Multi-layered materialsPriceModerateHighLowMid-rangeModerateLowScratch ResistanceGoodExcellentPoorModerateGoodPoorChemical ResistanceGoodPoorPoorModerateGoodPoorThermoformingYesNoNoNoLimitedNoDurabilityHighHigh (brittle)LowModerateHighLowPorosityNon-porousPorousNon-porousNon-porousSome porosityNot applicableApplicationsThe flexibility and superior surface finish make acrylic solid surface ideal in workplaces, medical facilities, homes, fitness centers, and hospitality. The applications are endless as their use depends on the user's creativity. Here are some of its applications:● Furniture: Tables, Seating, Storage, and MoreModern furniture needs a sleek, artistic element that appeals to the eye. Acrylic solid surfaces' thermoforming capability enables the crafting of flawless-looking table tops and chairs. Skilled workers can manufacture closets or storage cabinets for homes, fitness centers, or medical facilities.● Bathroom: Sanitary ProductsThe non-porous surface of acrylic solid surfaces prevents mold and bacteria from growing. It is ideal for places with high hygiene requirements. Manufacturers use its thermoforming capability to produce bathroom countertops, shower walls, bathtubs, shower pans, vanities, and other accessories.● Arts and Design: Trendy InteriorsInterior designers can utilize acrylic solid surfaces to produce sculptures, light fixtures, wall hangings, or other creative projects. Like natural stone and mosaics, acrylic solid surfaces are available in various colors and designs. Their versatile colors make them ideal raw materials for interior design.● Partitions and Dividers: Open AtmospherePartitions and dividers are standard in offices or homes to create an atmosphere of privacy. Acrylic solid surfaces are light and challenging, which is ideal. Acrylics make it convenient to develop open yet divided rooms.● Laboratory Countertops: High Hygiene and Chemical ResistanceOwing to the high hygiene characteristics of acrylic solid surfaces, they are the ideal material for forming laboratory countertops. However, lab users must protect the acrylic solid surface from petroleum-based products, ammonia-based chemicals, and acidic material.● Whiteboards and Dry Erase Surface: Education and OfficesBesides furniture and countertops, acrylics are ideal for whiteboards and dry-erase surfaces in education. Jolting down ideas and sharing valuable information between pupils and undergraduates is best with a surface that remains steadfast against scratches or damage.Acrylic Solid Surface ThicknessManufacturers produce acrylic solid surfaces between 6mm and 30mm. High-end manufacturers can produce acrylic solid surfaces with a tolerance of 0.5mm. It allows for a perfect surface finish with exquisite quality for premium builds.The thickness can be a vital factor in selection, as thicker material is hard to bend during thermoforming but excellent for flat countertops. Users can opt for different thicknesses depending on their applications. Here are the major categories of acrylic solid surface thickness. ❖ Bendable and Thin Sheet (6mm-12mm):❖ Balancing Weight, Durability, and Aesthetics (12mm-15mm)❖ Extra Strength and Substantial Look (15mm-30mm)FAQs1. How to clean Acrylic solid surface?A warm, soapy solution is the best and most gentle way to clean an acrylic solid surface. If scratches damage the surface, use sandpaper, buff, and polish for effective results.2. Which household chemicals can damage acrylic solid surfaces?Avoid petroleum-based chemicals such as WD-40. Ammonia-based cleaners or highly acidic cleaners can also damage acrylic solid surfaces. Oven cleaners can also etch the surface. So always try your cleaner inconspicuous area before applying it to the main surface.3. Where can I use a solid acrylic surface?Acrylic solid surfaces have wide-scale applications. Artisans can use it for furniture, decorative elements, bathroom sanitary products, storage cabinets, wall fittings, trendy ceilings, dividers, whiteboards, and more.4. Is marble or granite better than acrylic solid surface?Naturally occurring marble or granite is ideal against scratches and chips but is heavy and easily etched with chemicals. Marble and granite surfaces are high maintenance, whereas acrylic solid surfaces are non-porous, thermoformable, lightweight, and easy to maintain.5. What are the precautions for using a solid acrylic surface?Acrylic solid surfaces are low-maintenance. However, use trivets and coasters to avoid heat damage. Use gentle soap and warm cleaner. Use a cutting board and avoid dropping sharp or heavy objects. Keep away from direct sunlight.

Are you interested in transforming your bathing experience by bringing a modern-day oasis to the comfort of your home? Discover a luxurious freestanding solid-surface bathtub. While the use of bathtubs dates back to the Indus Valley civilization (3300-1300 BCE), its modern form was first commercially made available by the Mott Iron Works Company in 1842. The industry has come a long way from high-maintenance cast iron to convenient solid-surface bathtubs.This blog post concerns solid surface bathtubs compared to other alternate materials. From medieval times to contemporary interior designs, bathtubs evolved in shape and material technology. If you want to buy a solid surface bathtub but still have questions about the right material choice, this blog post is for you. First, we will analyze the common problems with bathtubs to better judge material characteristics. Later, explore bathtubs with solid surfaces like copper, cast iron, fiberglass, stone resin, and more!Common Material-Associated Problems in BathtubsEveryone wants to own a house that can be a place to relax and recharge their energy. However, an unforeseen bathroom repair or maintenance requirement can cause little free time from our busy lives to become tragic. To make well-informed decisions on bathtub materials, here are common problems associated with various bathtub materials:● Mold: Fungi that Loves HumidityMold is a fungus that develops in a humid environment with oxygen. Bathtubs provide the ideal conditions for spreading mold by tiny reproductive cells called spores. Mold needs a surface to cling to, as it is naturally present in the air. Some bathtub materials enhance mold production, while others prevent it altogether.● Bathtub Cracks: Blame the Installer?Typically, bathtubs crack when the plumber does not correctly install them during construction. The uneven support can lead to cracking. Some materials are more susceptible to cracking than others. However, some materials have enough thickness to prevent cracks from developing.● Hardwater: Stains that Don't Go!The minerals in hard water can deposit a layer over your bathtub. It can disrupt the color scheme and cause the bathtub's surface to dull. Non-porous bathtubs are less likely to form the layer, but prolonged use can lead to hardwater stains.● Chipping: Direct DamageAny hard and heavy material can cause the bathtub material to chip away, which is a material that breaks away from the bathtub's surface. For example, a full shampoo bottle falling from a height can cause chipping on some bathtub material.● Rough TextureAs time passes, the bathtub surface can become rough. Usually, bathtubs with thin finish layers can become bumpy. It can also result from using incompatible chemicals on the bathtub surface. We will discuss chemical compatibility later in the material sections.Solid Surface Bathtubs: Modern Luxury with ConvenienceSolid-surface bathtubs are the staple of modern, contemporary looks. They add elegance and sophistication to the interior design and provide diverse options catering to any body type. Acrylic solid surface bathtubs have the best price-to-performance and feature ratio.♦ Solid Surface Bathtub BasicsThe term solid surface is primarily associated with solid bathtubs inside and out. A typical solid surface tub can weigh around 135-230Kg. They consist of 100% acrylic or a combination of acrylic, shards of stones, binding agents, and pigments. The acrylic solid surface bathtub is also known as a stone resin bathtub. Every manufacturer has their own technique and resin mixture.♦ Manufacturing Process of Solid Surface BathtubsIndustries manufacture solid surface bathtubs using various techniques. The process involves multiple operations to achieve a solid body and a premium finish. Here is the manufacturing process of a solid surface or stone resin bathtub:1. The manufacturer first prepares the base material using premium acrylic resin (a PMMA and MMA compound) mixed with quartz, limestone, aluminum, bauxite, or marble dust. At this stage, the material is in liquid form.2. The liquid mixture then goes into molds with gaps that match the thickness and shape of the final bathtub product.3. Now, the pre-designed mold is closed and allowed to cool and cure in suitable temperature and humidity conditions.4. Removing the mold results in a roughly shaped free-standing bathtub.5. The bathtub then undergoes cutting, grinding, and sanding operations to achieve the desired shape.6. A high-quality gel coat is applied to the stone resin bathtub (solid surface) to protect and produce a high-quality finish.♦ Material Characteristics of Solid Surface BathtubsSolid-surface bathtubs have a solid construction without any joints or patches. The acrylic mixed with minerals provides a solid shape that does not easily chip away. According to the 2015 International Plumbing Code, adopted by New York State, the maximum temperature flowing out of a faucet should not be above 49C, which is below the heat distortion temperature of solid-surface bathtubs.Here are the key characteristics of a solid surface freestanding bathtub made with ISO resin with 1000-grit aluminum hydroxide and LR brand pigments the material:- Tensile Strength: 50 Mpa- Tensile Modulus of Elasticity: 2900 Mpa- Elongation at Break: 5%- Bending Strength 80 Mpa- Impact Strength 12 KJ/m2- Heat Distortion Temperature 50 ºCPros and Cons of Solid Surface BathtubsPROSCONS✔ Non-Porous Mold Free Surface‒ Aluminum Powder Can Make It Heavy✔ Resistance Against Chipping‒ High Heat Exposure Can Cause Damage✔ Convenient Transport and Handling‒ Low Maintenance but Potential For Scratches✔ Extremely Low Probability of Cracking   Alternate Bathtub Materials: A Range of OptionsLet's dive into other material options for bathtubs. There are tons of low-budget and premium material options. However, we are in search of the perfect material that will enhance your household aesthetics and keep your bathroom low-maintenance. Here are some alternate bathtub materials to solid surface bathtubs:1. Porcelain-Enameled SteelThese are some of the most common designs in rental houses and budget hotels. Due to their multiple design options, such as a corner, double-ended, fitted, drop-in, alcove, and free-standing, porcelain-enameled steel, they make an ideal budget chemical-resistant bathtub option. In comparison to solid surface tubs, porcelain-enameled steel bathtubs are hollow.▪ Manufacturing & Characteristics: Steel Sheet and PorcelainThese bathtubs typically start with steel sheets. A large steel sheet is pressed using a machine to get its final shape. Manufacturers coat it with porcelain to protect the steel from corrosion and ensure the product's longevity. After the coating, it is heat treated to allow the porcelain to stick to the steel surface.   ▪ Pros and Cons of Porcelain-Enameled SteelPROSCONS✔ Budget-Friendly Option‒ Requires Plumbing Expertise✔ Easy to Handle Lightweight‒ Prone to Chipping and Dents✔ Non-Porous Porcelain Surface‒ Cracks Can Form with Time 2. Fiberglass: Lightweight and AffordableIt is the lightest material available for bathtub manufacturing. It is also the most convenient installation and affordable option in the bathtub category. A typical fiberglass bathtub weighs around 32kg (70lb). ▪ Manufacturing & Characteristics: Fibers and Polymer ResinThe process starts by using a mold. Then, a production worker sprays a gel coat onto the mold, and the layering of fiberglass starts. Multiple fiberglass layers are applied and impregnated with resin to provide strength. The whole assembly is allowed to cure. The manufacturer performs the sanding, polishing, and necessary finishing, which results in the final product.   ▪ Pros and Cons of Fiberglass BathtubPROSCONS✔ Easy to Install‒ Breaks Easily✔ Repairable‒ Improper Installation Can Cause Failure✔ Color Variations‒ Lower Heat Retention 3. Copper: Premium Medieval MaterialCopper is a well-known material in conductors like wires and circuits. It is soft by nature and has high conductivity. Intricate carvings and exquisite designs are a niche use of copper. Even though it has excellent characteristics, it costs a fortune to own one. The medicinal properties of copper and its antimicrobial capabilities have been well-known for ages.▪ Manufacturing & Characteristics: Pure CopperCopper is a soft, malleable metal that is easy to bend and carve. Skilled copper artisans can form premium designs. A large sheet of copper is either pressed into the shape of a bathtub, or an artisan can use special tools and techniques to create the shape. Unlike the solid surface bathtub, copper bathtubs may require welding and finishing jobs.▪ Pros and Cons of Copper BathtubPROSCONS✔ Antimicrobial Ultra Hygienic‒ Premium Price Tag✔ Easy to Clean‒ Careful Handling✔ Corrosion Resistant✔ Quickly Adopts to the Water Temperature4. Cast Iron: Heavy Duty MaterialIron is directly affected by the percentage of carbon. Cast iron consists of more than 2% carbon, resulting in durability and hardness. It is relatively affordable compared to copper but costs more than a solid surface bathtub. The malleable property of cast iron makes it susceptible to damage in tensile stress. ▪ Manufacturing & Characteristics: Tough Under CompressionThe cast iron process is similar to that of solid-surface bathtubs. It starts by pouring melted iron into a mold, allowing it to cure. Hammering Iron into shape is impossible, so it requires careful cutting, grinding, and finishing. Due to its high hardness, cast iron is difficult to handle and can break under stress. ▪ Pros and Cons of Cast Iron BathtubPROSCONS✔ Lasts a Lifetime‒ Porous Material Can Affect Appearance✔ Easy to Repair‒ Brittle Under Tensile Stress✔ Resistance to Chipping‒ Heavier Than Other BathtubsFinal VerdictConsidering all other alternatives of solid surface bathtubs, solid surface bathtubs top the chart in all aspects. No wonder their popularity is ever-growing. Here are the key points why solid surface bathtubs are superior to other materials:● A non-porous surface prevents the formation of mold or stains from hard water.● Retains heat, unlike copper or cast iron bathtubs.● Easy to clean using a mild detergent.● It is ideal for some quiet time as there is minimum impact noise● Resists cracking, chipping, and breaking.● The solid surface bathtub is an ideal lightweight alternative to heavy metal bathtubs.● Ease of installation and longevity.
