I'm going with dark grey to match the bath and a little darker than the fine edge on the tile. Therefore, it's down to personal preference between ultra modern and more traditional. I would prefer a more traditional look with a claw foot bath, but that's up to you. Something like this:- Sanctuary Bathrooms - Hampton Traditional Or you may prefer something a little more modern:- Soakology - Britton Aqua Whatever you go for, I think it's important to match the grey of the unit and the grey of the bath otherwise it's going to get too busy in there with the different greys. What sort of shower enclosure are you thinking? This was the widest longest tray I could find (1200mm) - would have preferred a little longer say in the region of 1500mm x 1000mm - due to the space available - Living Roc Shower Tray Smoked Glass Shower Enclosure

Please see below some inspirations you may find helpful. I would agree with Man About The House in his post above, to get the right vanity unit for your bathroom will be good to see some pictures and the colour schemes.

Stick it all on Facebook marketplace - that's what I do 🤣 I have found a single hairpin leg I can buy on ebay 😃 - black or gold! Not sure if brushed gold but the tiles behind will be black. And white and the sink unit will be the light/mid grey to match the floor. Although the sink will have gold fittings,im wondering if the leg could be black as its against a black/white tile and I have a black mirror above the sink? Who knows. I have one on my dining table so going to try it begore buying 🤣 The front depth of the shelf is a 3" but I can make it deeper if needed
