How to install a lyons shower base
Installing a new shower base is a great way to upgrade your bathroom and create a spa-like experience right at home. As an expert in home renovations and upgrades, let me walk you through the complete process of installing a Lyons shower base step-by-step. I‘ll provide plenty of details, statistics, and insider tips so you can take on this project like a pro!
Before we get started, you‘ll need to gather the following materials:
- Lyons shower base (size and style of your choice)
- Mortar or thinset
- Grout
- Caulk/sealant
- Tile backer board
- Galvanized screws
- Tile (sized to your preference)
- Tile spacers
- Tile edging pieces
- Tile adhesive
- Tile grout
- Grout sealer
- Caulk gun
- Safety gear (gloves, goggles, knee pads, etc.)
- Basic tools (hammer, screwdriver, tape measure, level, etc.)
Make sure you have all of these materials on hand before beginning the installation process. Having everything you need ahead of time will make the project go much more smoothly!
The first step is preparing the shower area for the new base installation. Here‘s how to get started:
Turn Off Water Supply
It‘s crucial to turn off the water supply to the shower area before installation. This prevents leaks or other water damage during the process. Locate the shut-off valves for the shower and turn them all the way off. Then, turn on the shower briefly to ensure water is completely off before proceeding.
Remove Existing Materials
If there is an existing shower base or wall surround, use a pry bar, hammer, and other demolition tools to completely remove these materials. Take your time and make sure all old surfaces are fully cleared out. Wear safety goggles and gloves during demo to protect yourself.
Inspect the Floor
Thoroughly inspect the subfloor after removal. Look for any signs of damage, uneven surfaces, or lack of structural support. The floor needs to be even, dry, and sturdy enough to support a shower base.
- Pro tip: Use a 4 foot level tool to check for flatness across the floor area.
Repair Subfloor as Needed
If the subfloor is damaged, use new plywood and construction adhesive to patch and level the area. Severely damaged subfloors may need complete replacement. Proper floor prep prevents future shifting or cracks in your new shower base.
Install Framework
If walls need framing, use 2×4 lumber to create a solid framework for the shower area. Ensure the framework is plumb and square using a bubble level tool. Sturdy framing provides a strong surface for installing backerboard and tiles.
Proper prep of the shower area ensures your new base will have a solid foundation for many years! Don‘t cut corners here.
Once your shower area is prepped, you can begin installing the tile backer board:
Measure and Cut Backer Board
Measure each wall and cut the backer board to size using a sharp utility knife. Leave a 1/8" gap between boards and for corners. Carefully cutting each piece ensures a perfect fit.
- Pro tip: Save time by asking for pre-cut boards at your home improvement store.
Apply Mortar to Walls
Use a notched trowel to spread a layer of latex-modified thinset mortar evenly across the shower walls. Apply in straight rows for best coverage. The ridges will help adhere the backer board.
Press Boards Against Mortar
Firmly press each backer board piece against the mortar, using spacers to maintain even 1/8” gaps. Work methodically around the shower for full coverage.
Secure with Galvanized Screws
Use galvanized backer board screws to firmly secure boards into the wall studs. Space screws 8 inches apart for best stability. Avoid over-tightening.
Allow Mortar to Cure
Let the thinset mortar cure for a full 24 hours before moving on. This allows complete drying and bonding to the wall.
With tile backer board properly installed, you‘ll have a durable, waterproof surface ready for tiling!
Once the backer board has fully cured, we can move on to installing the actual shower base:
Thoroughly Clean Subfloor
Use a shop vac and rag to remove all dust or debris from the shower floor area. Ensure the subfloor is completely clean and dry before applying mortar.
Apply Thinset Mortar
Use a 1/4” notched trowel to apply a generous bed of thinset mortar evenly across the shower floor. Extend mortar 2” up the walls for an overlapping waterproof barrier.
- Pro tip: Look for lightweight "shower mortar" for easier application on floors.
Install Shower Base
Carefully lower your new Lyons shower base into position over the mortar bed. Press down firmly so the base adheres properly in the mortar.
Check for Level Surface
Use a 4 foot level across the top of the base to ensure it‘s perfectly even. Adjust as needed by lifting the base edge and adding/removing mortar.
Allow Curing Time
Let the thinset cure fully for 24 hours without applying weight or other materials. This ensures the base is solidly bonded to the floor.
A shower base installed on a properly sloped mortar bed will serve you well for decades. Don‘t rush this important step!
Before we move on to tiling, it‘s absolutely crucial to waterproof the shower walls:
Apply Waterproofing Membrane
Use a paint roller to apply a liquid waterproofing membrane to all surfaces of the backer board. Cover seams between boards thoroughly.
- Pro tip: Look for membrane with built-in mold resistance for extra protection.
Apply Second Coat
Once dry, apply a second complete coat of membrane over the first coat. Ensure all bare spots are fully covered.
Let Membrane Dry
Allow membrane to dry fully according to manufacturer directions, usually 6-12 hours. Proper drying ensures maximum water protection.
Seal Corners and Seams
Use silicone caulk to seal all corners, edges, and seams thoroughly. This provides a water tight seal.
Waterproofing is a mandatory step! Don‘t skip it or you risk expensive leaks and moisture damage later on.
This is where the real transformation happens. Let‘s get tiling!
Plan Your Tile Layout
Decide on the size, shape, and pattern of your tiles. Use tile spacers to plan even grout line spacing. Cut border and niche tiles beforehand.
- Pro tip: Draw out your tile plan on paper and bring it to the store to get help purchasing the right quantities.
Mix and Apply Tile Adhesive
Mix high quality polymer-modified tile adhesive according to package directions. Use a notched trowel to spread it evenly across the surfaces to be tiled.
Press Tiles into Adhesive
Starting at the top, press tiles firmly into the adhesive one section at a time, using spacers to maintain even alignment. Check periodically for straight lines.
Allow Tiles to Cure
Let tile adhesive cure fully for 24 hours before grouting or sealing. This allows complete drying and bonding of tiles.
Take extra care during tiling to properly space, align, and install border tiles for flawless results.
Grouting is what finishes off your tile job:
Mix and Apply Grout
Mix non-sanded grout as directed on package and work it thoroughly into tile crevices using a rubber grout float. Remove any excess.
- Pro tip: Look for grout with built-in mold resistance for easier maintenance.
Let Grout Dry
Allow grout to dry completely for 72 hours before sealing or getting wet. Slow drying promotes strongest grout.
Seal Tile and Grout
Apply a penetrating grout sealant to all grout lines and tile surfaces. Allow to dry fully. Sealing prevents staining and damage.
Properly grouted and sealed tiles will stay looking like new for many extra years! Don’t skip sealing.
We‘re in the home stretch now with just some finishing touches:
Reinstall Plumbing Fixtures
Reinstall any showerheads, valves, or soap holders using silicone caulk to provide a watertight seal.
Apply Perimeter Caulking
Caulk all corners and seams between tile and base with flexible, waterproof silicone. Smooth the bead with a wet finger.
Let Caulk Dry
Allow caulk to cure fully for 24 hours before use. Turn on water supply and carefully check all joints for any leaks.
Add Final Touches
Install any shower benches, niches, shelves or grab bars as desired. Enjoy your stunning new shower!
Perimeter caulking keeps water flowing exactly where you want it – down the drain! Take your time with this last crucial step.

Here‘s to many years of relaxing, spa-like showers!
Let‘s go over answers to some of the most common questions about Lyons shower base installation:
Do I need mortar under the shower base?
In most cases, yes. Mortar provides important support and drainage slope for a shower base. However, some bases may have their own pre-attached mortar layer. Always check manufacturer requirements.
How much slope should the shower floor have?
The standard recommendation is 1/4" of slope per foot distance toward the drain. This ensures proper water runoff with no pooling.
What size and type of drain do I need?
Use a 3" diameter shower drain made for the thickness of your shower base material. Lyons bases work with either clamping ring or compression fit drains.
Can I install on a second floor or above garage?
Yes, provided there is adequate structural support below. Consult an engineer to be sure the framing can support a shower‘s weight when full of water.
How long does mortar need to cure for?
Allow all thinset mortar beds to cure fully for 24 hours before continuing with other steps. This allows complete drying and bonding.
What‘s the easiest way to cut a shower base?
Use a jigsaw with a blade rated for fiberglass, acrylic, or other base material. Work slowly for clean cuts. Wear safety gear.
Can I add grab bars or a seat to my Lyons base?
Absolutely! Just be sure to properly waterproof any screw holes with caulk/sealant.
How often should I re-caulk the shower surround?
Plan to re-caulk at least every 1-2 years, or whenever you notice missing caulk, cracks, or leaks developing.
