Can I tile my own bathroom?

Yes, tiling is legal DIY anywhere in the UK. The hand-overs are the kit around it: an electrician connects underfloor heating, a Gas Safe registered engineer moves gas appliances, and a plumber moves pipes or a toilet.

Can I tile straight onto plasterboard?

Often, within its weight limit. The Tile Association's guide gives 32 kg/m² for unskimmed 12.5 mm plasterboard and 20 kg/m² once it's skimmed, counting tile, adhesive and grout. Board makers may allow more, so check theirs.

Do I need to tank a shower?

Anywhere that gets soaked regularly needs a waterproof layer behind the tiles, because grout lets water through. Use one maker's system and follow its instructions.

Will your lessons teach me to tile?

They teach the knowledge behind the work: backgrounds, adhesives, setting out and what to hand over. They're learning content, not a qualification, and they don't replace practice or a tiler's judgement.

For homeowners

DIY tiling: backgrounds, adhesive and when to call a pro

Tiling your own splashback or bathroom wall is legal anywhere in the UK. Most DIY tiling problems start before the first tile goes on: the wrong background, the wrong adhesive or no plan for the cuts. Here's what's worth knowing, and the jobs that belong to someone else.

Our wall and floor tiling path is in public beta: some lessons are still being checked.

What's worth understanding first

Each of these has its own guide.

Can the wall take it?

Every background has a weight limit. Skimmed plasterboard and gypsum plaster take less than bare plasterboard, and the weight counts the adhesive and grout as well as the tile. Heavy porcelain can go over the limit.

The right adhesive

Adhesive bags carry class codes like C2TE S1. They tell you how well it grips, whether tiles slide, how long you have to work and how much it flexes. Porcelain usually needs a class 2.

Plan the cuts

Start from the middle of the wall, not a corner, and you can usually avoid thin slivers at the edges. A level line and a marked batten keep the rows straight.

Water behind the tiles

Tiles and grout aren't waterproof. In a shower, the wall and floor behind them need a waterproofing (tanking) system, made to work together by its maker.

Jobs that belong to someone else

Tiling isn't restricted work, but the rooms you tile have kit that is.

Electric underfloor heating

You can learn how a heating mat is laid and protected, but connecting it to the electrics is a job for an electrician. In England and Wales a new circuit is notifiable under Part P, and so is work in the zones around a bath or shower. The main routes: an electrician registered with a competent person scheme does the work and notifies it, or you tell building control before the work starts. England also has registered third-party certifiers, and Wales lists more notifiable work than England. Scotland and Northern Ireland have their own building rules.

Gas appliances

Moving a gas cooker, fire or boiler so you can tile behind it is gas work: use a Gas Safe registered engineer, in Great Britain and in Northern Ireland.

Pipes, wastes and toilets

Moving water pipes, a waste or a toilet is plumbing work, and some water fittings work needs your water supplier's permission first. Get a plumber in before you tile.

Old tiles and old adhesive

Some old floor tiles, textured coatings and black bitumen adhesives contain asbestos. If you're not sure, get it tested before you break anything up.

Cutting safely, and when to call a tiler

Silica dust

Cutting or grinding tiles makes fine silica dust that damages lungs. Cut wet or with an extractor, and wear a properly fitted mask rated for fine dust. A manual cutter makes far less dust than a grinder.

When to call a tiler

Wet rooms, heated floors, natural stone, large-format tiles and big open floors are where DIY goes wrong most often. A tiler will also spot a background that needs fixing first.
