How To Upgrade A Bathroom Without Removing Tiles

Why Leave The Tiles Where They Are?

Taking tiles off a wall is the dirtiest part of any bathroom job. It is noisy, it fills the house with dust, and in older Scottish homes the plaster very often comes away with the tiles, so the wall has to be rebuilt before anything new can go on it.

If the tiles are sound, leaving them in place means:

• Less mess and less noise, which matters in a flat with neighbours through the wall.
• Less time with the bathroom out of use.
• No surprise bill for re-boarding or re-plastering.
• Less waste going to the tip.

It is not right for every room, and we will come to that. But where it suits, it is a sensible way to get a new-looking bathroom.

Option One: Wet Wall Panels Over The Tiles

Wet wall panels (sometimes written wetwall, or called shower panels) are large waterproof boards with a decorative face: marble, stone, concrete, wood or plain colours. They are a product we fit every week, and they can be bonded directly over existing tiles.

How it works:

1. The tiles are checked, cleaned and degreased so the adhesive can grip.
2. Panels are cut to size, including holes for the shower valve and pipes.
3. Each panel is bonded to the tiles with panel adhesive, and the joints between panels lock together or are covered with a slim trim.
4. The bottom edge is sealed to the bath or shower tray, and corners and ends are finished with trims.

The result is a smooth wall with no grout lines. That is the real win: grout is where tiled showers go mouldy and where water eventually finds its way through. A panelled wall wipes clean in seconds.

You can see panelled rooms in our bathroom gallery, and handle the samples at our showrooms.

Will It Work On Your Walls?

Panels over tiles only last if what is underneath is sound. These are the checks that matter.

• Tap the tiles. Knock gently across the wall with your knuckles. A dull, solid sound is good. A hollow, rattly sound means the tile has let go of the wall. One or two can be dealt with. A whole area means the tiles should come off.
• Look for damp. Crumbling grout, a musty smell, staining, or mould that keeps coming back low down near the bath or tray can mean water is already behind the tiles. Covering that up traps the problem.
• Check the wall is flat. Panels are rigid. A wall that bows, or tiles that step in and out, will show through or leave gaps behind the panel.
• Allow for the thickness. Panels add to the wall, so the fitter has to plan for it around window sills, door frames, the shower valve and the edges of the bath or tray.

The shower area is where this matters most. If the tray or bath moves, or the seal along it has been leaking, that needs fixing first. New panels on top of a moving tray will not stay watertight.

Other Upgrades That Leave The Tiles Alone

If the tiles are staying and you are not covering them, there is still a lot you can change.

• Renew the grout and silicone. Rake out tired grout and re-grout, then replace every bead of silicone. It is cheap, and it makes a bigger difference than most people expect.
• Replace the suite. A new toilet, basin and bath on the same pipe positions usually needs little or no tile work. Be aware that a new bath or basin of a different size can leave a gap where there are no tiles behind the old one.
• Swap the pedestal basin for a vanity unit. You gain storage, and the unit hides the untiled patch and the pipes.
• Change the shower and screen. A modern thermostatic shower and a clean glass screen in place of a curtain lifts the whole room.
• New flooring. Good quality vinyl can often be laid over a sound, level floor.
• Lighting, mirror and towel radiator. A backlit mirror and a tall towel radiator are quick changes with a big effect. Any electrical work in a bathroom needs a qualified electrician.
• Panel the ceiling. Ceiling panels cover flaking paint for good and take new downlights neatly.

What about tile paint? It can freshen tiles on a dry wall, such as behind the toilet. In and around the shower it tends to peel, so we would not rely on it there.

When The Tiles Really Should Come Off

Sometimes going over the top is the wrong call, and a good fitter will say so.

• There is a leak or damp behind them. It has to be found and fixed, and the wall dried out or replaced.
• Lots of tiles are loose or hollow. Panels are only as secure as what they are stuck to.
• You are changing the layout. Moving the shower, bath or basin means new pipes in the wall.
• You want a wet room. A wet room needs the floor and lower walls waterproofed from scratch.
• The room is already tight. In a very narrow room or shower recess, the extra wall thickness may stop a standard tray or screen fitting.
• The plaster behind has failed. Common in older homes, and only obvious once you start tapping.

In those cases a full refit is the better value, because you only pay for the job once.

What It Costs And How Long It Takes

There is no set price for a panels-over-tiles upgrade, because it depends on how much wall is being covered, which panels you choose and what else is being replaced. What we can say is that wall panels go up faster than tiles and are often cheaper fitted than full-height tiling, and skipping the strip-out saves labour and waste costs on top.

For comparison, most full bathrooms we fit cost between £5,500 and £14,000, and are fitted in 3 to 6 days. An upgrade that keeps the tiles and the layout sits at the quicker, simpler end of that kind of work.

If you would like to spread the cost, finance is available from £22 a week, subject to status.

How We Can Help

At a free design visit, a designer checks the tiles and the walls, measures up, and helps you plan what to keep and what to change. If the tiles can stay, we will say so. If they cannot, we will explain why before you spend anything.

Everything is fitted by trusted installers and all workmanship is guaranteed. Have a look at our bathrooms page for styles and ideas, or our modern bathrooms page for the clean, panelled look. We work across Scotland, including Glasgow and Kilmarnock.

Quick Answers

Can you put wet wall panels over tiles?

Yes, if the tiles are firmly fixed, reasonably flat and there is no damp behind them. Loose tiles must be dealt with first.

Do the tiles need to be removed around the shower?

Not always. But if the seal along the tray or bath has been leaking, that area should be opened up and put right before panels go on.

Will panels over tiles make the room smaller?

Only slightly. The main thing is planning for the extra thickness around windows, door frames and the shower valve.

Can you tile over tiles?

It can be done on a sound wall, but it adds a lot of weight and thickness. Panels are lighter and leave no grout to maintain.

Is painting bathroom tiles worth it?

On dry walls it can be a cheap refresh. In the shower it tends to peel, so it is a short-term fix at best.

How long do wet wall panels last?

Fitted and sealed properly, good panels give many years of service with nothing more than a wipe down. Check the maker's warranty for the panel you choose.
