I bought it as an off the shelf from Highgrove bathrooms and then just paid an installer. A lot of installers won't do them because if your walls are not dead straight you can end up with a lot of silicone packing them out which isn't a great look and then people don't want ot pay for the installation. Fortunately these walls were brand new so they were dead straight.
Yay or nay? Toilet showers!
Rain shower and hand shower
Is a curbless shower a good idea?
