Wall Panels and Surrounds for Walk-In Tubs: Acrylic 3-Panel Kits, Cultured Marble, and PVC Tiles

Updated September 2026

Wall panels and surrounds for walk-in tubs from Ella's Bubbles come in four families: acrylic 3-panel shower wall kits in solid white, marble and stone prints and CNC engraved patterns, tub height acrylic surround kits including the 6-panel kit with built in shelves, the SMC 12-piece subway pattern wall kit, and grout-free tongue-and-groove PVC wall tiles. Cultured marble panels were offered in the past. None of these is a tub specific surround molded to one model. They are wall systems that you cut and fit to your space, so the key rule is that whatever you choose must match the tub footprint exactly and overlap the tile flange and deck so water stays in front of the wall. Availability of each line changes over time, so please check the current shower and accessories pages on ellasbubbles.com or ask the team before ordering.

Acrylic 3-Panel Wall Kits

The acrylic 3-panel shower wall kit is a 60 inch back panel and two side panels of multilayer acrylic that give you a waterproof, easy to clean surface that resists stains and scratches. The current product pages list shower height kits at 40 by 60 by 98 inches, 38 by 60 by 96 inches and 40 by 60 by 105 inches, in solid white glossy, high resolution marble and stone prints such as Carrara, Calacatta and Desert Stone, and CNC engraved patterns such as Subway, Flowstate and EllaWave. An earlier kit with two 36 by 97 inch side panels and one 60 by 97 inch back panel installs the same way. The installation manual for the CNC engraved pattern kit is published at this link, and the kits are shown at ellasbubbles.com/showers/three-panel-kit/marble-stone-acrylic-shower-wall-kits/. The full step by step, including the silicone dot pattern and the 24 hour bracing, is in installing the wall kits, surrounds and tiles.

The video above demonstrates safe cutting of the acrylic panels. When you cut acrylic panels to size for an odd-shaped alcove or a window, the cut edges are finished with trim strips or sealant from a tile or building supply store, since Ella's Bubbles does not supply custom edge pieces.

This short shows the CNC engraved acrylic panels, where the tile or wave pattern is machined into the glossy acrylic so there are no grout lines to scrub. They install exactly like the flat 3-panel kit.

Tub Height Surround Kits and the 6-Panel Kit

For a walk-in tub in a three wall alcove where the tub itself is the wet area, the product pages also list tub height 3-panel surround kits in the same finishes, sized around 40 by 48 by 60 inches, plus the solid white glossy 6-panel kit that adds two molded corner shelves. The 6-panel kit is the one surround with built in shelves, and like the shower kits it is trimmed on site to the alcove. Which height you need depends on whether you shower standing in the tub; if you do, the guide to showering in a walk-in tub helps you plan the column, screen and wall height together.

SMC 12-Piece Subway Wall Kit

The SMC kit is eight side panels and four back panels, each 24 inches high, that stack four rows to a 96 inch wall for a 36 by 60 inch alcove, with a 9-piece option for a 72 inch height. The panels have an overlapping flange and a molded subway tile pattern, so there are no grout lines, and they go up bottom row first on 100 percent silicone.

Cultured Marble Wall Panels

As the video explains, Ella's cultured marble travertine shower walls are made from a natural quartz and granite composite with a gel coat surface, for a natural look and feel that is durable and easy to clean. They come as multi-piece surrounds of eight, six, or four panels, and the panels are light enough to be carried and installed by one person. The panels are glued over drywall, plaster, painted walls, Durock, or even existing tiles. The edges are factory finished for seamless joining, but they can be trimmed and cut for a custom fit. Please note that this line has had limited availability, and matching replacement panels are not always available, so if color matching matters to you, ask the team about current stock and consider ordering a spare.

Grout-Free Tongue-And-Groove PVC Tiles

The PVC grout-less tiles are a simple way to upgrade a shower or bath enclosure. They can be placed over new or existing surfaces and fit together with a snug tongue-and-groove connection. The video shows the full sequence:

  1. Measure carefully.
  2. Score and then snap the tile to get the precise piece you need.
  3. Apply adhesive to the back of the tile. The team recommends Loctite construction adhesive.
  4. Place a thin bead of silicone at each joint to ensure a watertight seal.
  5. Set the tile and snap it into place, then continue to the next.

The tiles measure 12 inches by 24 inches and come 8 tiles to a box, and one box covers 16 square feet. To estimate your order, measure the square footage of the walls you plan to cover, divide by 16, and round up, adding a little extra for cuts. Finishes have included Carrara White, Carrara Iris, Marble Beige, Corintia Marble and Brushed Concrete. Current styles are listed at ellasbubbles.com/showers/accessories-and-fixtures/tongue-and-groove-shower-wall-tile/.

Fitting the Surround to Your Tub

  • Wall surround kits must match the tub's exterior footprint exactly. An ill-fitting surround creates gaps that let water behind the walls, which is a serious long-term problem.
  • Panels and tiles should overlap the tile flange and the flat deck, and every joint gets silicone caulk. The tile flange and wall finishing article covers that detail, and the glue-up tile flange kit explains which length to choose.
  • Ella's Bubbles does not provide corner trim pieces, edge trim, or replacement window trim. Tile shops carry suitable trims for corners and cut edges.
  • For some models, such as the Transfer60, there is no model-specific surround. Many customers use tile or a universal surround from another supplier, sized to the footprint.

Cutting Around a Window

If there is a window in the installation area, you cut the back wall panel to create the opening for the window, and the existing window trim is cut as needed. Ella's Bubbles does not provide replacement trim, so plan to finish the window edges with trim and sealant from a local supplier. Measure the window twice and cut the panel on a flat, supported surface.

Common Questions

Do you have a surround for my tub?
Ella's Bubbles offers wall systems rather than surrounds molded to one tub. The acrylic 3-panel kits, the tub height surround kits, the SMC subway kit and the PVC tiles are all cut and fitted to your alcove, so any of them can finish the walls around an Ella tub as long as the footprint matches.
Can the panels go over existing tile?
Cultured marble panels can be glued over existing tile, and the PVC tiles can go over new or existing surfaces. For the acrylic 3-panel kit, solid ceramic tile can stay if it is firmly attached, but plastic tile must come off; follow the published installation manual and have your installer confirm the wall condition.
How many boxes of tongue-and-groove tile do I need?
Each box holds 8 tiles covering 16 square feet. Divide your wall area by 16 and round up. The team often suggests around 8 boxes for a typical full height enclosure, and about three boxes for a tub height 60 inch alcove, but it varies with your layout.
What adhesive do I use?
Loctite construction adhesive on the back of the PVC tiles, with a silicone bead at every joint. The acrylic 3-panel kit is glued with 100 percent clear silicone only, never screws or nails.
How do I handle corners and cut edges?
Ella's Bubbles does not offer corner trims. Use corner trim or waterproof seal strips with a high-quality silicone caulk from a tile supplier.
Can I get a sample first?
Samples are not routinely sent; the product photos and videos are the reference. If a sample matters for your project, ask the team.
Do you carry flooring or real stone panels?
No. Ella's Bubbles carries acrylic and PVC wall systems, and in the past cultured marble. Flooring and natural stone come from a tile supplier.
Is there a tool to plan the shower walls?
Yes, the shower builder at ellasbubbles.com/shower-builder/ lets you lay out a base, walls and accessories for your alcove. For anything the builder does not cover, ask your Ella dealer or the team at (800) 480-6850.
Which panel height do I need for a walk-in tub?
If you only bathe, a tub height surround kit finishes the alcove. If you shower standing with a column or hand shower, choose the full height 96 to 105 inch shower kits so splash stays on a waterproof surface. The wall kit sizes at a glance article lists every kit dimension.
