is this tub able to have a deck mount faucet?

Hi! The bathtub is
designed for free standing faucets. However we have had customer with some of
the wider rim bathtubs customize the tubs to their needs with a rim faucet.
This would depend on the tub rim size and the size of the faucet as to whether
this customization would work. Our narrower rim tubs would lack the space
needed for any rim style faucet, please be advised. I hope this is
helpful!

can a 225 lb 6' man fit in this tub?

Hello, the tub manufacture
has had no experiences with tubs failing due to weight and is confident in
assuring performance up to 330lbs. Weights above this, the customer must take
responsibility for the use. I believe a 6ft tall person will fit but it will be a little tight. This tub has an interior length of 60.5 inches and an interior width of 25" at the widest point. I do have a colleague who is 6'4" tall and loves the size of the 67" Parva. See item link below:

@babs598 Probably is the better answer to your question, comfortably is a matter of opinion. I went with the Wyndham 63" because of the wider base and higher gallon capacity.
