The bathroom is one of the places in the house where most falls happen, and climbing out of a high-sided bath has a lot to do with it. Replacing it with a non-slip shower tray, flush with the floor or with the smallest possible step, solves the problem in one or two days, without renovating the whole bathroom.
It is also a very common change in holiday lets and second homes on the coast: a roomy shower is quicker to clean, uses less water than a bath and looks better in the listing photos.
We have been renovating bathrooms between Sotogrande and Estepona for more than 15 years. We take out the bath, fit a made-to-measure tray, tile the space to match and install the screen, with new taps and all the rubble removed.
