DH and I are renovating our house. Our bedroom is big with a pitched roof. We would like to put in an en suite shower room but the only place it can go is right in the centre on one side of the room where the apex of the roof is. So it doesn't take up too much floor space, we are planning on it being only as wide as the shower tray, with a sink unit right opposite the shower and a small area for drying off in between. However this will mean the shower tray (90x120cm) will be completely surrounded with solid walls on three sides. Does that sound OK or will it feel like we are showering in a cupboard do you think?
