Showrooms ALWAYS have most if not all the upgraded options installed in addition to cleverly sized pieces of furniture. That's how they sucker in buyers who can't look past cosmetic features. Most of my clients are always surprised on what they actually get is 4 blank walls. All of a sudden, the included granite countertops and/or stainless steel appliances don't look as nice.

Was tile something standard or extra you had to pay for? These days tiled bathroom floors are usually standard and the purchase contract should make mention of the developer substituting equivalent materials (ie: different design/colour, etc). Tile to linoleum isn't an equivalent material.
