9. Handheld showerhead. If you are still mulling over your showerhead options, don’t leave out the handheld ones. While they can be a bit unwieldy with their hoses and pivoting heads, they have a distinct advantage over their fixed-in-place cousins: They make it easy to clean the shower stall. The showerhead that comes from the ceiling? Supercool, but good luck washing the walls of your shower with it. Same thing with showerheads on the wall. A nice compromise between the two, if you can afford it, is to get one of each with a diverter. That will allow you to use the main showerhead most of the time, the handheld one for cleaning and both at the same time if you want a spa experience.10. Epoxy grout. It is more expensive, unwieldy to work with and stinks. But epoxy grout has a big benefit over its sanded and nonsanded cousins: It makes it difficult for mildew to grow, and liquids have a hard time penetrating it. We have been installing it frequently in master showers and at kitchen backsplashes (where food and grease can splatter) with great results.Tell us: Do you have other things beyond these 10 that you can’t live without in your bathroom?
