How to Choose Waterproof Flooring for a Bathroom
Bathrooms are one of the hardest-working rooms in any home. Between daily showers, splashes around the sink and the occasional overflow, your bathroom floor needs to handle moisture without warping, lifting or growing mould. Choosing the right waterproof flooring for bathrooms means you get a floor that looks great, feels comfortable underfoot and stands up to everything a busy bathroom throws at it.
In this guide, we cover the main types of waterproof bathroom flooring available, what to look for when making your choice, and how to pick the right option for your space and budget.
Types of Waterproof Flooring for Bathrooms
Vinyl and Cushion Vinyl Flooring
Sheet vinyl flooring is one of the most popular choices for bathroom floors, and for good reason. It is 100% waterproof on the surface, comes in a huge range of styles (from wood-effect to tile-effect designs) and is soft and warm underfoot. Cushion flooring adds an extra layer of foam backing for comfort and insulation, making it ideal if you prefer a softer feel when stepping out of the bath or shower.
Because sheet vinyl is laid in a single piece (or with heat-welded joins), there are no gaps for water to seep through. This makes it one of the most reliable waterproof options for family bathrooms and en-suites alike.
LVT and SPC Flooring
Luxury vinyl tiles (LVT flooring) and stone plastic composite (SPC flooring) are both excellent choices for waterproof bathroom flooring. They come as individual tiles or planks that click together, giving you the realistic look of wood or stone with full waterproof protection.
SPC flooring in particular has a rigid stone-based core that will not swell or warp when exposed to moisture, making it a strong choice for bathrooms, wet rooms and shower areas. Bathroom LVT offers a similar level of performance with a slightly softer feel, and both options are available as click flooring that you can install without adhesive.
Waterproof Laminate Flooring
Traditional laminate was never suited to wet areas because its fibreboard core would swell on contact with water. However, newer waterproof laminate flooring ranges use water-resistant or fully waterproof cores and sealed edges to handle bathroom moisture. If you love the look and feel of laminate, check the product specifications carefully: look for products labelled "waterproof" rather than just "water-resistant" for use in a bathroom.
Waterproof Bathroom Carpet
If you prefer a softer, warmer floor, waterproof bathroom carpet tiles are designed specifically for wet environments. Products like Flotex use tightly packed vertical fibres on a waterproof backing, so they dry quickly, resist mould and can even be machine washed. They are a fantastic option for anyone who dislikes cold, hard floors in the morning.
What to Consider When Choosing Waterproof Bathroom Flooring
Waterproof vs Water-Resistant
"Water-resistant" means the material can handle occasional splashes but may still be damaged by prolonged exposure or standing water. "Waterproof" means it will not absorb water at all. For a bathroom, always aim for fully waterproof flooring.
Slip Resistance
Look for flooring with a textured surface or a certified slip-resistance rating (R10 or higher for domestic bathrooms). Many vinyl and LVT products include a textured top layer designed for wet areas.
Comfort and Warmth
Cushion vinyl and Flotex offer the most warmth underfoot. SPC and LVT can be paired with underfloor heating. Sheet vinyl with foam backing provides decent insulation without additional heating.
Installation and Subfloor
Click-fit SPC and LVT can often be laid over existing hard flooring without adhesive. Sheet vinyl needs a smooth, flat subfloor. Check underfloor heating compatibility before buying.
Style and Budget
The best waterproof flooring for your bathroom also depends on the look you want. Modern vinyl and LVT come in convincing wood, stone and tile effects that suit any bathroom style, from contemporary to traditional. There are great options at every budget: sheet vinyl tends to be the most affordable, with SPC and premium LVT at the higher end.
Frequently Asked Questions
What is the best waterproof flooring for a bathroom?
It depends on your priorities. For the most reliable waterproof seal, sheet vinyl or cushion vinyl is hard to beat because it has no joins. For a premium look with individual tiles or planks, SPC flooring offers a fully waterproof rigid core that handles heavy moisture without any issues.
Can you use laminate flooring in a bathroom?
You can, but only if you choose a product specifically designed to be waterproof. Standard laminate will swell and warp in a bathroom environment. Look for laminate with a waterproof core and sealed edges that is explicitly rated for bathroom use.
Is vinyl flooring fully waterproof?
Yes. Vinyl flooring is waterproof on its surface. Sheet vinyl laid in a single piece offers the highest level of water protection because there are no seams. Click-fit vinyl tiles and planks are also waterproof on the surface, though you should ensure joins are properly sealed in very wet areas like walk-in showers.
What is the best flooring for a wet room?
For a fully open wet room, wet room vinyl flooring or safety flooring with a slip-resistant surface is the most practical choice. SPC flooring also works well in wet rooms thanks to its completely waterproof rigid core.
Do I need underlay with waterproof bathroom flooring?
It depends on the product. Many SPC and click-fit LVT products come with an integrated underlay, so you do not need a separate one. Sheet vinyl and cushion vinyl do not require underlay at all. Always check the manufacturer's installation guide for the specific product you are using.
