A Complete Guide to Custom Stone Resin Shower Pans

The popularity of stone resin shower pans is primarily due to their luxurious feel. As the name suggests, the material is a combination of actual crushed stone, which can be dolomite, marble, or limestone dust, and polymer resin. The presence of stone makes the material dense with high heat retention. As the hot water warms up the shower pan, it remains warm underfoot. Owing to their direct installation on the floor with no gap, the material is acoustically deadening. The water striking the stone resin shower pan doesn't make a loud noise like the cheap fiberglass.

The modern stone resin shower pans provide a waterproof interface in bathrooms, protecting the structure while providing a contemporary or minimalist aesthetic. Instead of off-the-shelf designs, luxury home owners and hotels demand bespoke fittings with customized dimensions. Since the material is molded into shape, it allows much more complex geometries in comparison to the typically standard fiberglass or acrylic pans.

This article is a complete guide to custom stone resin shower pans, covering advantages, customization techniques, cost analysis, customization process, and finally, an installation guide.

Advantages of Custom Stone Resin Shower Pans

Using a premium-grade material like stone resin to produce shower pans comes with loads of advantages. Their production nature makes them highly versatile.

↑ Durability and Aesthetic

Stone resin materials are highly dense with a 2.03 to 2.8 g/cm³ density. In comparison to natural stone, the addition of resin into the mixture gives it higher compressive strength and impact resistance without the higher weight. It makes transportation convenient and installation much easier. Their non-porous nature helps resist mold, mildew, and bacteria without the need for chemical sealants.

To seamlessly integrate with the shower area, custom stone resin shower pans come with tiling flanges or upstands to ensure that the transition from the pan to the wall remains water-tight, protecting the building structure. The dense polymer gel coat provides a chemically inert barrier that protects the material underneath from common household chemicals like hair dye, vinegar, lipstick, and red wine.

↑ Modern ADA-Friendly Design

Manufacturers consider spatial engineering and biomechanics aspects when designing their stone resin shower pans. The first hurdle is the safe entry into the shower for individuals using wheelchairs or walkers. The modern shower pans sit perfectly flush with the bathroom subfloor without the bump, which is vital to avoid hesitation, cognitive confusion for users with dementia, or tripping hazards.

Older designs had a drain in the middle, which required slopes from all sides to the center to ensure proper draining. Modern stone resin-based shower pans come with trench drains that are typically aligned with the backwall. It allows designs to follow a simple one-directional 1:48 slope to break water surface tension and ensure wheelchair movements for users with balance issues. ADA understands that a perfectly flush shower pan with the floor is challenging to construct. Therefore, it allows 1/2 inch of bump or less when bevelled at 1:2.

What Can You Customize in a Stone Resin Shower Base?

Customization is one of the biggest advantages of stone resin shower bases. Their manufacturing process involves molding techniques. It unlocks massive customization potential that natural stones can never offer. Let's dive deeper into the customization capabilities of the stone resin shower base.

✦ Dimensions and Layout Options

In case of historical walls or site preservation restrictions, layouts can have awkward alcoves, neo-angles, or irregular shapes. Manufacturers can map the area to produce a specific mold matching the layout or use CNC machining to match highly specific geometries. The final result is a seamlessly integrated stone resin shower base. These bases can have dimensions from 70 cm squares to 250 cm for large room integration.

Other customization options include selecting the tiling flange sides and basin depth. The manufacturers can provide pre-fabricated tiling flanges to the sides of the custom shower base as required by the installation site. Users can opt for the ultra-low profile flush designs or the classic basin designs for water retention.

✦ Drain Position, Finish, and Color Customizations

The drain position in the traditional shower base material was limited to the center. This can be challenging at some sites where structural concrete beams, floor joists, or established plumbing stacks conflict with the design. Stone resin shower pans have the ability to cast a drain wherever you need. Manufacturers can adjust the internal slope to ensure proper draining.

Stone resin shower pans come in different surface finishes. They can be high-gloss with friction but havea sleek, reflective, and modern look. In comparison, users can also pick matte finishes, which offer a higher coefficient of friction with better grip. These are far better than applying aftermarket grips that can trap bacteria.

As the stone is crushed and mixed into the resin, there are tons of color options, including RAL color codes, slate black, concrete grey, or earthy tones. Users can also pick texture variations, which can be high-gloss, pebbled, or brushed marble effects.

How Much Does It Cost to Customize a Stone Resin Shower Base?

The idea of having a completely customized stone resin shower base is exciting. It comes with massive advantages that off-the-shelf products can not offer. However, it's vital to see if it comes with a reasonable price tag.

Let's compare readily available products in the market with fully customized bespoke shower pans. For hypothetical purposes, take the example of a standard 48" x 60" rectangle:

• Base Cost: The cost of crushed stone and resin required for casting is around $1,500
• Geometric Complexity: If the design is different from a standard shape, then the manufacturer will use a custom mold, which will add 20% to the base cost, which will be +$300 for our hypothetical design.
• Safety and Accessibility: To ensure ADA compliance, like flush zero-threshold entry or a specific 2:1 bevel, the additional cost would be +$250
• Aesthetic and Texture: Moving away from standard white pans towards premium color options like deep black or marble effects, +$150 would be added.
• Structure Engineering: To relocate the drain and adjust the slope, there is no additional cost,t as it is already covered in the base cost.

Final Calculation:

$1,500 (Base Volume) + $300 (Geometric Premium) + $250 (ADA Tolerances) + $150 (Color/Texture) + $0 (Custom Drain Placement) = $2,200 Total Cost

While the $2,200 price tag of the custom stone resin shower base looks significantly higher than the standard $400 fiberglass pan, the value lies in the lifecycle. You will save on drain replacement, plumbing relocation fees, and structural damage.

The Customization Process

To fully grasp the customization process, we can divide it into easy-to-understand steps:

Step 1: Blueprint and Measurement Submission

This process involves the client or the architect providing sketchy dimensional drawings and floor plans, as well as plumbing constraints, to the manufacturer.

Step 2: CAD Engineering

The manufacturer calculates the internal slope gradients of a Computer-Aided Design (CAD) 3D model, which is the calculation of internal slope gradients with a specific custom size to promote proper drainage.

Step 3: Client Sign-Off

The client looks through the technical drawings and gives his approval to physical color and texture samples prior to the commencement of production.

Step 4: Preparation of Templates and Molded

A customized mold is made, commonly with CNC-milled high-density foam or modular steel formwork.

Step 5: Thermal Curing

The mixture containing mineral and resin is poured into the desired mold. Constant stirring is applied to ensure that there are no bubble entrapments. After that, the mold is placed in a heated curing oven to ensure dimensional stability. Some manufacturers may use vacuum casting processes to ensure no internal weak points.

Step 6: Final Steps

After the mixture cures inside the mold, the mold is taken apart. The pan is then hand-finished and tested for water flow and friction.

Installation Guide for Stone Resin Shower Trays

After we have our custom or off-the-shelf stone resin shower tray arrive. We can start the process of installation. Here is a short guide to installing shower pans:

Pre-Installation Preparation

• Subfloor Integrity Check: Ensure that the surface that you are going to prepare is structurally stable, leveled, and free from debris.
• Dry Fitting: Place the shower tray into the area to see alignments and confirm drain pipes are centered to the pan hole.
• Stud Notching: When the pan has tiling flanges built into it, label and notch the wooden wall studs in such a way that the bottom of the pan is even with the framing.
• Joist Load Assessment: Verify if the floor joist can handle the load of the shower tray after installation.

Step-by-Step Installation Procedure

• Application of the Mortar Bed: Spread a good, smooth, even coat of the manufacturer's recommended thin-set mortar or sand-cement mix on the subfloor with a notched trowel.
• Laying the Tray: Gently place the heavy resin base into the wet mortar bed, making the assembly fit into the mortar bed without any force.
• Leveling: Press hard and place a large spirit level on all its edges and diagonals. Make sure that the perimeter is completely horizontal. The gradient would be built in to take care of the water flow.
• Drain Connection: Attach and screw up the drain flange by using a continuous line of 100% silicone sealant on the rubber gasket to ensure there are no micro-leaks.
• Perimeter Sealing: Seal expansion cracks between the edges of the tray and the floor/studs with a high-grade polyurethane sealant that is waterproof.
