Mermaid panels have been a familiar name in UK bathrooms for years, and now under the Wetwall banner, the range has only got stronger. If you have been searching for a genuinely waterproof, grout free alternative to tiling that will not cost a fortune, the Wetwall Mermaid Collection is very likely the range you keep landing on. This guide covers what makes it stand out, what it actually costs, and five specific decors worth shortlisting for your bathroom.
What Is the Wetwall Mermaid Collection?
The Wetwall Mermaid Collection is a range of waterproof bathroom wall panels built around a strong plywood core, finished with a high performance decorative surface layer and a durable backing layer for balance and stability. Mermaid panels were a well established, independently trusted brand in their own right for years before joining forces with Wetwall, and the quality and reputation that built that trust has carried straight over.
Unlike tiles, mermaid wall panels give you a single continuous, seamless surface with no grout lines at all. That single detail is behind most of the reason people search for this range in the first place. No grout means no scrubbing, no discolouration and no mould creeping into joints over time.
Are Wetwall Mermaid Panels Waterproof?
Yes. Mermaid panels are designed to be 100% water resistant, protecting the wall behind from moisture damage caused by everyday splashing, steam and condensation. The plywood core construction gives the panel genuine rigidity and a solid, premium feel that lighter weight panel systems cannot match, while the surface layer and backing layer work together to keep water out entirely rather than simply resisting it at the surface.
This makes the Mermaid Collection suitable for shower enclosures, over bath shower walls, wet rooms and full bathroom wall installations, as well as kitchens and utility spaces where a genuinely waterproof surface is needed.
What Sizes Do Wetwall Mermaid Panels Come In?
Mermaid panels are available in five width options, 585mm, 880mm, 900mm, 1185mm and 1210mm, all at a standard 2420mm height and either 10mm or 11mm thickness depending on the specific decor. Panels come with either a square edge or a tongue and groove profile, giving flexibility depending on how you want the joins between panels to sit.
A standard 1210mm wide panel weighs around 26.3kg, which gives you a sense of the genuinely solid, substantial feel this range has compared to lighter PVC alternatives.
How Much Do Wetwall Mermaid Panels Cost?
Mermaid panels sit in the mid market bracket, more premium than basic PVC boards but noticeably more affordable than solid stone or high end laminate ranges. As a rough guide, panels have historically worked out at around £90 for a 1.2m x 2.4m board, though current pricing across the wider Mermaid range varies by decor and width.
Compared with tiling, homeowners can typically expect to save in the region of 25% or more on a like for like bathroom project, largely because mermaid panels do not require a specialist tiler, no grouting stage is needed, and installation time is dramatically shorter.
5 Best Wetwall Mermaid Collection Decors for UK Bathrooms
Here are five standout designs from the Wetwall Mermaid Collection worth considering for your next bathroom project.
Bianco Marble
An ivory decor with soft beige and brown marble veining running through, giving a serene, neutral warmth that suits almost any bathroom style. Bianco Marble is one of the most popular choices in the entire range for anyone wanting a timeless, elegant finish without going too bold.
Marble Palazio
A dark, dramatic marble decor in contrasting deep grey with striking white veining throughout. Marble Palazio brings a genuine sense of luxury to a bathroom and works particularly well as a statement wall behind a bath or vanity.
Welsh Slate
Part of the stone and concrete styles within the collection, Welsh Slate delivers a more industrial, textured look, ideal for bathrooms leaning toward a contemporary or rustic aesthetic rather than a polished, classic finish.
English Oak
A light, warm oak decor with a fine, detailed wood grain that brings genuine rustic charm to a bathroom space. English Oak is a strong pick for anyone wanting the warmth of natural timber without any of the moisture risk real wood would bring into a wet room.
Vintage Concrete
Rusty browns, reds and greys combine in this decor to create a genuinely dramatic industrial look. Vintage Concrete suits bathrooms designed around a bold, urban feel and pairs particularly well with matt black fittings and fixtures.
Wetwall Mermaid Panels vs Tiles
The comparison most people are actually trying to make when they research this range is Mermaid panels against traditional tiling, so here is the honest breakdown.
Tiles require grout, and grout requires ongoing maintenance, resealing and cleaning that never fully stops. Mermaid panels are grout free from day one, giving a smooth, wipe clean surface that stays looking fresh with minimal effort. Installation is also considerably faster, since there is no tile cutting, spacing or grouting stage involved, and panels can typically be fitted directly over existing tiles, avoiding the mess and cost of stripping the wall back to bare plaster.
Where tiles may still appeal is for buyers who want an entirely bespoke, tile by tile pattern or who are working with an unusually shaped wall that benefits from smaller format pieces. For the vast majority of standard bathroom walls and shower enclosures, however, Mermaid panels offer a faster, cleaner and more cost effective route to the same finished look.
What Guarantee Do Wetwall Mermaid Panels Come With?
Every panel in the Mermaid Collection is backed by an industry standard 15 year manufacturer’s guarantee, provided the panels are installed correctly using the recommended adhesive and sealant. This is a genuinely reassuring figure for a mid market panel range and reflects the confidence Wetwall has in the plywood core construction holding up to years of daily bathroom use.
