Any home improvement project should have surface protection protecting all surfaces. During construction, accidents happen and for a couple bucks you can protect the floor, tub, cabinet, counter, and carpet. One damaged fixture or floor will bring your cheap home improvement project and turn it into an expensive nightmare. Protect your fixtures during the construction process. Hope this helps
I have found that using the concrete surface already present, or using a concrete overlay saved money. We put a decorative stamped overlay in our bathroom, stained it with a terra cotta acid stain color, and sealed. It was done quickly, and at a fraction of the cost for tile.
