Maybe do the 2 bedrooms with carpet and then just match the othere 2 spaces with the same tile. I think trying to match and miss the laminate would be worse.

Cork is an excellent carpet replacement product. It is warm and quiet underfoot. It comes in two formats: A floating click-together format for 'dry' areas and a glue down tile for wet areas such as bathrooms and mud rooms. Yep...you heard me. The glue down cork tile is 100% water proof. As in MORE water proof than vinyl click together products. How? The glue down cork tiles are butted together (no grout lines) when installed. They are then coated x2 with water based polyurethane. The poly seals the seams to create a continuous sheet of cork. The only areas of concern (as with ALL floors in a bathroom) would be at the walls where cork meets drywall. I'm a cork flooring expert. I've done this more times than I can count. A situation like yours were you do NOT want to refinish the entire house because two rooms had issues. Cork is an oak. It has many of the same colour tones as White and Red oak. In fact it starts out quite orange (sigh...ignore that phase of it's life...it doesn't last very long) but soon calms down to a lovely soft yellow which is IDENTICAL to the current laminates you have. Here's how I would do it: I would pick a floating floor that has an IDENTICAL glue down tile option. I would install the floating floor in the bedroom. This gives you the 'total' floor height that you need to match. Now you remove the bathroom flooring and lay in new plywood OR cement backer board (cork doesn't care) to raise the floor up. Now you glue down the cork tile (6mm or 8mm) so that it matches the existing floating floor. Finish the floor in two coats of polyurethane and Voila! A continuous floor with minimal effort. A glue down tile floor (if you hire this part out) is going to cost (labour plus materials) the same as a porcelain tile installation. That's roughly $12-$15/sf. Sounds horrible until you realize you have 30sf to cover...now that's not too bad! A floating cork floor will cost (roughly) the same as a HIGH END vinyl floor installation ($4-$5/sf for materials + $3/sf for labour). www.icorkfloor.com Cork Flooring Tiles Glue Down - Forna Silver Birch 6mm Flooring (icorkfloor.com) Floating Cork Floor - 12mm Forna Floating Cork Flooring (icorkfloor.com) Those are just and example of how to get a continuous floor in two different formats of cork.

I would do a 4-5 inch white

I would think the most popular configuration would be what is typical for a house with three bedrooms. It would have a master bedroom with an ensuite of a nice size. A nice shower would be preferred by most people rather than a tub and small shower or a tub shower combination. The two guest bedrooms would share a bathroom and that bathroom would have a tub shower combination. I have always lived in dense urban areas (Manhattan and now Los Angeles high rise condo) and that would be the configuration for your target audience. Having three small master bathrooms would be a configuration if you were renting to three unrelated people who needed to share the rent and personally I don't think that is the optimum tenant as families and empty nesters are more reliable and probably long term versus constantly moving as young unrelated professionals would.
