Tiny bathroom

Building a small bathroom into an outbuilding so that guests can sleep there, how best to arrange something little but charming ? Shower, loo, basin possibly a bidet too. What would be an acceptable amount of space for that ?

My bathroom is about 6ft square. I have a 900mm quadrant shower, I wouldn't want anything smaller TBH.

I wouldn't bother with a bidet in a guest bathroom, especially if you have a shower. They are a bit niche aren't they? I've never seen one in anyone's house in my life!

I grew up in a house with a tiny bathroom. There was a bath, basin and toilet, with floor space about 60cm x 60cm. It was just fine.

I haven't seen anyone have a bidet installed in the last thirty years! If you are that short of space, why bother?!

I had one that was 1.2m by 2m which is as small as you possibly can fit (no bidet, but you could have a japanese toilet with incorporated bidet if you wanted)

Don’t have to have a bidet, DH grew up with them, I didn’t. I’ve used them in various countries and find them most useful for a quick wash when dealing with periods. We have friends who visit from places where bidets or plumbed in hoses are standard, hence wondering whether to bother. Think 18 year old dd might want to have the space as her own though, and she isn’t bothered either way, although she has used them abroad.

Shower one end, toilet the other, sink in the middle facing the sliding doors - if it’s just an ensuite then having it opening into the room would be useful but then the doors can give privacy if necessary

It could open into the room or into a central entry space, there will be a room on the other side. Imagine an open rectangle with a door in the centre and windows either side. One side will be a bedroom, the other side storage space, so we need to work out how best to configure this.

Yes dd is used to Japanese toilets so maybe that is a good idea.

I think we definitely have enough space for 2m by 2m, could go a bit larger if necessary.

We don’t have mains sewage, so a built in bidet also helps minimise tissue going down the loo.

We have a sink, bidet loo and extremely small shower in 1200mm by 1200mm so you will have space in 2m by 2m

My bathroom is small, approx. 1.5m x 1.5m.

We have a 1200 quadrant shower, toilet and small WC sink/vanity.

There's a small 30cm2 space at the end of the shower where we have hooks, towel rails and a small hamper. It has a bi-fold door and no radiator (but doesn't get cold anyway as theres a really hot radiator right outside the door in the hallway).

Also on our old street of Victorian houses most had added an upstairs bathroom in the old landing airing cupboard space and they where only 1.8m x 0.9m

The doors opened outwards into the hallway and they had a toilet at one end and a small 900 square shower at the other and a small WC sink in the middle. They where tiny and narrow but worked.

Here's a photo of one of them.

2x2 is plenty if you have full head height all over. Including for a separate bidet.

Really helpful, thanks everyone. It’s good to see an image as it is helping me imagine the space. Our bathroom isn’t large but it’s larger than this one will be , and has a bath and an airing cupboard, I want to optimise the space for this smaller bathroom so that it’s nice to use and not too cramped.

You can get douche kits to save you taking up space with a bidet.

AllJoyAndNoFun · 14/02/2026 21:02

Mine is almost exactly that size with the added complication of a sloping ceiling which limits where you could have a mirror above a basin. This is what I'm doing - 80x 100cm quadrant offset enclosed shower tray , toilet and 100cm vanity with countertop basin on the right with counter space to the left of it and a double drawer underneath. Towel rail behind the door (door is at the bottom of the pic, next to the shower and opens inwards- the window is opposite it and takes up most of that top wall). HTH.
