Hi, Phoenix, I just went upstairs to measure my L shaped bath, turns out it is 1650, nice size. I had the bathroom completely refitted when I retired, with overhead shower with large/small heads, fitted wash hand basin /W.C. unit in high gloss white. It is the only bathroom in my three bedroom house, so I wanted to keep a bath, which I enjoy daily!
Our builders removed all skirting boards, door frames and window ledges, and put in PVC ?ceiling with downlights, tiled floor to ceiling and window ledges, put chrome edging around door, so nothing to paint in future, making it easier for advancing years. Taps are at one side so there is space for bath aid if required at later date.
I once fell coming out of the bath and had bad bruising, like the map of France, on my derriere! My friend, who is a nurse, advised me not to exit the bath from a sitting position cos you can slip while pulling yourself up, but to roll over onto your knees first, then straighten up holding on firmly to rail.
Hope this helps, enjoy your new bathroom!!
