Bathrooms
 
Bathroom remodeling costs scale according to:
size of the bathroom
complexity of structure or plumbing to be moved
the cost of the finish items such as vanities, countertop, plumbing fixtures, shower door, etc.

Remodeling costs for a 40-50 square foot bathroom can be divided in three levels (as a guideline of course) -

Reface - $2500-$5000
If the general layout and size of the bathroom is sufficient, and there is no water damage or structural issues, a "reface" project is often considered. The theme for this type of bathroom remodel is "cover, not replace."

 
- Replace vanity, countertop, and sink (in this case the most cost effective approach is the   pre-assembled vanity, granite countertop, and sink)
- Replace toilet
- Install new towel racks and hardware
- Update lighting and new exhaust fan
- Patch/texture existing drywall, repaint walls and ceiling
- Flooring and tub/shower tile remains intact.
 
New Layout - $6000-$13,000
The structure of the room is intact and there is a desire for some rearranging, such as moving the toilet and vanity locations to accommodate a modern floor plan.
 
- Move toilet location, move vanity location
- Install new vanity, countertop, sink
- Install new toilet
- Install new towel racks and hardware
- Update lighting and new exhaust fan
- Patch/texture existing drywall, repaint walls and ceiling
- Shower/tub location and wall tile remains intact.
 
Complete Tear-Out/Remodel - $14,000-$22,000
New floor plan and all new finished items. Completely change tub/shower unit and all associated tile, new glass shower enclosure, tile flooring. Make the neighbor jealous.
 
- Remove tub and create a large shower with shower enclosure and tile walls and shower pan   (using ceramic or porcalin tile, not natural stone such as marble or travertine)
- Install new tile flooring and tile baseboard (ceramic or porcelin)
- Install new vanity, countertop, sink
- Install new toilet
- Install new towel racks and hardware
- Update lighting and new exhaust fan
- Patch/texture existing drywall, repaint walls and ceiling
