Let‘s start by understanding what makes LuxStone special.

What Exactly is Kohler LuxStone?

Kohler offers a few different engineered stone materials, but LuxStone is the top of the line. It‘s made from a precise blend of crushed quartz, marble, and other premium natural stones that Kohler compresses under intense vibrations.

The result is an incredibly durable, non-porous solid surface composite. Unlike natural stone, LuxStone resists cracking and staining, all while retaining an elegant, polished stone-like look.

Here are some key traits that make LuxStone a luxurious yet practical choice for shower walls and floors:

• Extremely durable – Designed to last decades without signs of wear. Made to withstand daily use and accidental bumps better than fragile natural stone.
• Stain resistant – The non-porous surface makes it nearly impossible for dirt, soap scum, and minerals to penetrate or discolor the material.
• Easy to clean – Low-maintenance and simple to keep looking new with routine cleaning.
• Resists mold and mildew – With proper ventilation, mold won‘t grow on the surface.
• Custom sizing – Wall panels and bases come in multiple sizes and thickness options to fit your space.
• Color and finish options – Available in polished or matte finishes and calm, neutral color options.
• Matches Kohler fixtures – Designed to perfectly coordinate with Kohler plumbing fixtures and accessories.

While definitely pricier than acrylic or fiberglass surrounds, LuxStone delivers unparalleled luxury and peace of mind that it will stay looking flawless. The heaviness does mean two people are best for safe install. But as you‘ll see, with careful prep and patience, a DIY LuxStone installation is totally achievable.

How Much Does Kohler LuxStone Cost?

As a premium composite blending natural stone, LuxStone sits at the highest price point among Kohler‘s engineered stone materials. Here‘s a breakdown of typical costs:

• Shower bases: $800 – $1,200
• Shower walls: $1,200 – $3,500+
• Shower kits: $2,000 – $5,500

These prices are just for the raw materials—the walls, base, and threshold. Plumbing fixtures, tile, accessories, and most importantly, professional installation, can add thousands more.

For example, I recently quoted a customer on a mid-range job:

• LuxStone shower walls + base: $3,500
• Shower fixtures and tile accents: $1,200
• Installation and labor: $2,500
• Total project cost: $7,200

With those extras factored in, you can end up spending anywhere from $3,000 to $9,000+ for a complete LuxStone shower installation. It all depends on:

• Size of the shower (larger = pricier)
• Layout complexity
• Number of accessories like shelves and benches
• Plumbing and tile upgrades
• Your geographic location

But the materials themselves make up a significant portion of the cost. And with the right DIY approach, you can install LuxStone yourself and put thousands back into your pocket.

Necessary Tools and Materials

The beauty of LuxStone is you can install it using everyday household tools and common construction materials. No need for special saws or adhesives.

Tools You‘ll Need

• Tape measure
• 4-foot level
• Caulking gun
• Utility knife
• Jigsaw (for easier cuts)
• Power sander (optional, for smoothing cut edges)
• Drill
• Phillips bit
• Pry bar
• Dust mask & safety glasses
• Denatured alcohol (for cleaning)
• Grout float
• Mixing paddle and bucket

Materials You‘ll Need

• Kohler LuxStone wall panels and shower base
• Thinset mortar
• Caulk (100% silicone)
• Grout
• Construction adhesive
• Backerboard (if your walls need it)
• Shims
• Plumbing supplies – drain, pipes, and fittings
• Kohler shower fixture trims or accessories (optional)

Make sure you have all the tools and materials on hand before starting the installation. Safety gear like gloves, knee pads, and plastic sheeting for the floors are also a good idea.

Preparing the Shower Area

I can‘t stress enough how vital proper planning and prep work is for a smooth installation. You need to make sure the shower area provides a sound, waterproof surface for the LuxStone.

Here are the key steps I take when prepping a shower for new walls:

Inspect the substrate. The existing walls should be intact and moisture-resistant. If you see any damage, mold, or leaks, address those issues first.

Install backerboard if needed. Cement backerboard creates a waterproof, durable surface for the walls. If your walls are drywall only, adding 1/2" backerboard is highly recommended.

Map out the plumbing. Figure out exactly where your valves, shower head, drains, and any accessories will go. Mark these locations on the walls.

Build out framing. LuxStone panels mount directly to studs. Add any necessary 2×4 blocking where panels will attach.

Waterproof existing surfaces. RedGard or Kerdi membranes provide an extra moisture barrier on the walls and ceiling. Don‘t skip this!

Dam the entrance. Cut a 2×4 to width and wedge it in the shower entrance. This contains thinset when you pour the shower floor.

Take photos of the plumbing and measurements for easy reference. Thorough planning makes installation so much easier.

Step-by-Step DIY Installation Instructions

Once your prep work is complete, it‘s go time! Here is the process for safely installing the LuxStone panels:

Install the Shower Pan

The shower base provides the foundation for the walls. Kohler‘s bases are pre-sloped for proper drainage.

1. Dry fit the pan. Set it in place and check the fit. It should align with your plumbing.

2. Mix thinset mortar. I prefer the powdered type with an acrylic admix. The consistency should be fairly stiff.

3. Apply thinset to the subfloor. Use a 1/4" square notched trowel to spread an even layer where the pan will sit.

4. Set the pan. Carefully place it and press down firmly to adhere to the thinset below.

5. Let the thinset fully cure per manufacturer instructions, usually 24-48 hours.

6. Complete the drain hookup. Remove the 2×4 dam and finish connecting the drain pipe to the trap.

Install the Wall Panels

Now that your base is in place, shift focus to the wall panels. Take your time here for a professional fit.

1. Dry fit the panels. Make any cutouts for valves and niches using a jigsaw.

2. Caulk the inside of the curb. Run a bead of silicone along the inside corner where the walls meet the pan.

3. Apply thinset to the panel backs. Use a 3/16" V-notch trowel to cover the entire mesh backing.

4. Lift the panel into place. Carefully position against the wall and press firmly to adhere. Have someone help lift the heavy pieces!

5. Use shims to plumb the walls. Insert shims between studs and panels to level surfaces and prevent flexing.

6. Secure panels to studs. Drill pilot holes and use the provided screws to mount panels into studs top and bottom first, then across the field.

7. Repeat this process for the remaining panels, caulking all seams and corners thoroughly as you go.

Finish With Trims and Accessories

The trim and fixtures complete your LuxStone shower installation.

1. Install fixtures and accessories. With the panels securely mounted, install your shower valves, shelves, benches, and hardware.

2. Apply trim. Run a bead of adhesive on the mounting strips, position trim over the panels, and screw into studs.

3. Grout seams and gaps. Mix grout per instructions and pack it thoroughly into trim joints and along the floor.

4. Caulk corners. Use silicone caulk where the walls meet the shower base for a waterproof seal.

5. Let cure fully before using the shower. Enjoy your luxurious new space!

And that covers the complete installation process. It takes time and precision, but the results are so worth it.

Tips and Tricks from a Professional

After years installing tile and natural stone, I‘ve picked up some best practices that apply to DIY LuxStone projects:

• Carefully read Kohler’s entire installation guide. Don‘t skip any steps—this material needs proper handling.

• Have a helper. Extra hands make a big difference when moving heavy panels into place. Don‘t overexert yourself.

• Work slowly and double check as you go. Precision here prevents major issues down the road.

• Shim liberally between studs and panels. Shimming ensures your walls stay plumb and prevents flexing or cracking over time.

• Let thinset and grout fully cure. Waiting the full cure times is crucial for strength and waterproofing. Don‘t rush it!

• Keep valuables away from the work zone. Thinset and grout can stain floors, walls, and fabric. Use plastic sheeting for protection.

• Start accessories only after panels are secured. You don‘t want shelves or soap dishes interfering with panel placement.

• Caulk, caulk, caulk. Can‘t emphasize this enough—use 100% silicone caulk anywhere panels meet, along corners, and near fixtures.

Follow those tips and you can expect an installation that looks professionally done.

Common Mistakes to Avoid With LuxStone

It‘s easy to make mistakes installing LuxStone if you aren‘t methodical. Be sure to avoid these common pitfalls:

Rushing prep work. Not properly checking the substrate or plumbing layout can create costly issues down the road.

Uneven thinset application. This can prevent proper adhesion and lead to cracks as panels settle.

Forgetting waterproofing. Even small leaks can cause major damage without full waterproofing. Don‘t risk it!

Mounting panels incorrectly. Don‘t just screw into drywall—panels must attach securely to studs.

Not using shims. Shims prevent uneven surfaces and flexing that can crack grout lines. Always shim!

Gaps in caulk. Any pinholes or gaps along caulk lines can allow moisture behind the panels.

Curing too fast. Letting thinset, grout, and caulk fully cure is crucial for strength and water resistance.

Sloppy cuts. Precise, plumb panel cuts are needed to prevent tricky seams and alignment issues.

Scratching the surface. Always use plastic laminate guards when cutting panels to avoid scratches.

Caring for Your LuxStone Investment

Once installed, LuxStone requires very little maintenance. Here are my tips for keeping it pristine:

• Use a squeegee to remove water after every shower. This prevents buildup.

• For routine cleaning, use gentle dish soap, warm water, and a soft cloth. Avoid harsh chemicals.

• Vinegar and water works great for stubborn hard water stains or mildew.

• Re-caulk failing seals every 1-2 years to prevent moisture issues.

• Avoid abrasive pads or materials that can scratch the polished surface.

• Don‘t let soap, shampoo or cleaners sit too long on the surface. Rinse thoroughly.

• Limit exposure to harsh chemicals like bleach or drain cleaners.

With the proper prep and installation process, your LuxStone shower can stay flawless and provide daily luxury for decades to come. It‘s a big project, but absolutely DIY-friendly if you commit to following each step.
