Just to be clear, the only seal im talking about is from the tile surface to the top of the bath.
A non tanked room, tiled and sealed properly will be resistant enough for splashes from the bath, and if done well, the shower too. It obviously isnt good enough for any mid or long term submersion so there shouldnt be any ledges water can sit for a long time.
