Don't mix your tiles colours....It will feel bigger if you stick to just one colour. To be fair the window is enormous for the room so you already have something to break up the tiles! If you want the room to look more polished like a hotel bathroom I would have dark grout and add brushed steel trims. Have the trims on all the window corners and then add trim at picture rail height and another at skirting board height. Make sure the grout lines match on the floor and walls. If you are having a floating toilet and vanity make sure your towel rail pipes come out of the wall not the floor. In my opinion underfloor heating is well worth the minor cost. A slatted blind may trick your eye into thinking the room is bigger although I might investigate if your local glass merchant can fit a mirror behind the vanity- this could be fitted with the same fittings that would hold a glass balcony secured top and bottom of the window recess and you could have a simple roller blind behind it.

Hi Jen, good idea re the laundry - it would nicely "segregate" that functional space and open up all the rest as bathroom space. If you go that route, just check with a plumber that you don't cause any knock on issues with running a soil pipe from the back of the WC to the main soil stack (you really don't want those issues!!), and then make sure you do it in a way that doesn't lose light from that window. Regarding custom mirrors - the cheapest way is to get a local glazier to quote to make and install. Assuming it is just a single plain sheet you are looking for, the cost should not be too bad at all. Definitely get the glazier to install - it pays to leave the risk on their side, and they are experienced in handling the material. I've had a few bespoke glass splashbacks go "pop" on me, and there are few worse feelings... For what is a relatively piece of glass, make sure that there are no access issues to get it into the room (awkward bends round stairs or the like), or consider doing it in a couple of pieces. And if you are concerned about getting the best price, ask a couple of people to quote and look online too. And don't be afraid to haggle nicely - any glazier will try and squeeze a little extra margin if they can, so try and get it back! Try the online pricing tool at mirrorfit.co.uk for a quick feel of cost, or any of the other tools online.

What do you think about the bath and basin tap in brushed gold on the photos attached? Is this closer to your shower set in terms of finish and style? If you would be interested you could order them with us. But in case you would like something different, we suggest you at least have the same finish taps in the same area, meaning if you have a shower bath, than it would look better if both taps are in either brushed gold or black. But if you have a separate shower and bath, then you can easily opt for a brushed gold shower set and a black filler tap. And of course the same goes for the basin. Hopefully this helps! Good luck with your renovation!

Apart from the door position, my bathroom is about your size and layout and has a dual shower with drencher head above the bath. It doesn't look weird and I've had plenty of compliments! You've also got a higher ceiling than me so it should look much better. Most importantly, they are really nice to use. I say go for it. Regarding the towel rail, I went for a wall mounted one to make best use of the limited floor space. Just an idea. I've included a couple of photos so you can see what the shower might look like in a room your size. Please excuse the poor camera quality.
