Show Grout the Way Out
Install Mermaid panels without any need for tile, grout, seal, or trim.
Easy as 1-2-3-4
Installation Preparation & Requirements
Begin your project by inspecting your panels carefully for damage and verifying they are the correct size. Observe all local plumbing and building codes.
01 Gather Required Tools & Materials
Mermaid can be installed with standard woodworking tools. Download our installation guide for a complete list of tools and materials.
02 Prepare Existing Wall Surfaces
Wipe surfaces with a damp cloth so they are free of all contaminants and let dry. If installing over old tile, remove any loose tiles and rough up glossy tiles with a belt sander.
03 Remove Rough Plumbing & Fitting
Turn off hot and cold water supplies. Remove faucet handles, escutcheons, filler spouts and any other fixtures.
Dry Fitting the Tongue-and-Groove Panel System
Our patented tongue-and-groove panels let you estimate a rough "dry" fit for each panel on the wall. Remember to measure twice and cut once before you trim, place, and add adhesive.
01 Dry Fit Back Wall Panel(s)
Mark the seam or joint locations for later adhesive reference. For multiple panels, install the groove profile first. Keep a 1/8” gap from the tub deck, shower base, and walls for every panel installed.
02 Dry Fit Wing Panel(s)
Notice, one side of the panel has a bullnose edge that can be installed on the outside edge of the shower to give a finished look without wall trim.
03 Mark & Drill Plumbing Locations
Mark then drill where shower valves or heads come through the side panel using a hole saw large enough for the opening but small enough to be covered by the trim plates.
Panel Adhesive Application
Our high-quality adhesive allows you to quickly (and permanently) install our panels over any existing subwall including gypsum, fiberboard, cement, plaster, and even tile.
01 Apply Back Wall Panel Adhesive
Working with one panel at a time, apply one strip of panel adhesive vertically down the two sides of each panel and one row of adhesive horizontally across the top and bottom. This is a thick adhesive, so try an electric caulking gun for easier application.
02 Install Back Wall Panel(s)
Using suction cups, place the first rear panel onto the wall using the previously marked seam and joint locations for alignment assistance. Press firmly over the entire surface to ensure firm contact of adhesive. If additional rear panels are needed, place the second rear panel and leave a small gap to allow the tongue-and-groove to snap together.
03 Install Wing Panel(s)
Using suction cups, place the first rear panel onto the wall using the previously marked seam and joint locations for alignment assistance. Press firmly over the entire surface to ensure firm contact of adhesive. If additional rear panels are needed, place the second rear panel and leave a small gap to allow the tongue-and-groove to snap together.
04 Finishing And Trim (if needed)
Our designs can be trimmed and fitted using the bullnose edge to finish around windows, niches and exposed tile. When using our shower or tub kits, consider purchasing additional trim from your local hardware store.
Color Coordinated Sealant Application
Once your panels are up, it’s time to seal them with our reliable and long-lasting (and antifungal) sealant.
01 Apply Color Coordinated Sealant
Once all panels are securely in place and set, apply the sealant to all corners, seams between panels, and gaps between bottom panels. Wipe any excess adhesive from the panel with denatured alcohol.
02 Allow Sealant To Cure
Allow panels to cure for 24 hours before installing any shower accessories.
