Can you fit a shower in a tiny bathroom?

Short answer

Almost always. An 800×800 corner tray, a 760mm-deep alcove tray, or a wetroom-style corner with one fixed panel fit rooms people assume are bath-or-nothing. The real constraints are the door swing and the WC position — which is why the layout gets drawn before anything is quoted.

The smallest workable showers: 700×700 trays exist but feel penitential; 800×800 is the honest minimum for daily comfort; 900×760 in an alcove uses a chimney-breast recess beautifully. Sliding or bi-fold doors delete the swing space a hinged door demands, and a wetroom-style corner — level floor, one glass panel — fits where no enclosure will.

In the Victorian back-addition rooms that dominate our patch, the sequence that unlocks a shower is usually: rehang the door outward or slide it, shorten the bath to 1500mm or remove it, and use the freed corner. In the true micro-rooms — under-stairs cloakrooms being upgraded — the wetroom corner is often the only geometry that works, and it works well.

The honest limit: a shower needs a person-sized dry zone to towel off in, and a WC you do not sit on while showering. When a room genuinely cannot give both, we say so and look at the adjacent possibilities — a shower in the bedroom alcove next door sometimes beats a miserable one squeezed into the bathroom.
