Bathroom Reno - Opinions on freestanding tubs and shower size
I've started looking into a reno for my master bathroom and sketched up a plan (see below) but I am not sure about a couple of things.
Existing design:

Sketch of reno:

Note:
In the sketch, disregard the 3" clearance between the tub and its surrounding walls, this is going to increase to at least 4". I couldn't find an Ontario building code requirement for this, so this is per
International Residential Code: http://starcraftcustombuilders.com/bath ... .rules.htm
What I am not sure about:
1. Freestanding tub, are these really that hard to clean around? I've seen some people online suggest as much as a 1 ft of clearance all around the tub, and that anything less would make it a hassle to clean. I would think that if you left at least 4" that would be enough to squeeze a swiffer or vacuum extension into. Would we really be better off going with a built-in because of this potential problem?
2. Shower size, we want to go from a fairly small 36" x 36" neo-angle shower to a bigger shower stall, in this case something square with sliding doors to allow entry via the corner, but how much is big enough?
Had a discussion with a contractor and he initially suggested as big as 48" x 60", but we taped out those dimensions and it seemed way too big. Settled on 48" x 48" but are having second thoughts about that too now, because it could take a wall space for towel hangers and room to move around next to the freestanding tub we also plan to put in. I think the smallest we'd like to go is 42" x 42", but a middle ground would be 45" x 45" (if that is even possible).
Thanks for any input.
