Expansion or modernization? While the primary concern of many homeowners is to improve the appearance of the existing bathroom, others have larger plans. Some seek to create a master bedroom, master bathroom, and walk-in closet out of two smaller bedrooms. Still others want to create a bathroom suited to their own special needs, such as handicap accessibility. If the design change is radical, consider seeking the advice of a qualified architect.

What type of vanity, shower, and bathtub? Many homeowners prefer custom-designed and manufactured options. Others choose premanufactured, off-the-shelf alternatives. In general, off-the-shelf options are more cost effective. Additionally, a wide variety of material is used, including cultured marble, man-made solid surfaces, and natural solid surfaces, such as granite and tile. While prices of natural solid surfaces vary widely, they are usually more expensive than man-made solid surfaces.
