In terms of ease of use, especially for those elderly who need easy access, a walk-in shower could be a very good alternative to a full bath.
Excellent quality all-in-one shower cubicle designs are also perfect where space is at a premium, for example, if you want an en-suite addition to your bedroom and don’t have enough room to fit a full bathroom suite. A good example of the type of practical and well thought out design is the Saniflo Serenity Shower cubicle – it takes up no more floor space than a bath.
Obviously, if you are going to fit a shower into a place where there is no plumbing then you will need to consider the amount of work that may need to be done “behind the scenes” and what kind of difficulties could be encountered in the process. It would make sense in this situation to take on board the services of a professional plumber or a specialist fitted bathroom company.
