How do I bathroom / kitchen / extension? etc.

Thanks!

Tiles are Winckelmans encaustic cement, 70mm square. Using 'Ontario' beige and 'Red'. Found some dude who imports them direct from the French manufacturer for cheaper than the wanky UK 'Victorian mosaic' suppliers.

Gonna build a dogleg 'return' on the right side of the bath box, which will form an extended base for the shower glass. Was gonna have a matching tiled shower base, but swapped last minute for an orthodox shower tray (almost flush with floor) as I just cannot be arsed with the long-term maintenance of a shower base full of small-ish encaustic tiles and shitloads of grout lines.
