I thought it sounded like she was splitting it, but whatever she is doing sounds expensive.Confused too but I took it as the whole thing will be splash pool depth but that is odd too as a family pool and he won't be a toddler forever. Clear as mud.
Fitting an electric cover that I presume can go over the whole pool, or just roll back to expose the splash pool?
A complete kitchen; utility room and the pool alone will cost £1,000’s. Unless of course she is touting for freebies.
