Step 6 · Secure Tub to Studs

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Once the tub is perfectly level and set (allow mortar to cure if used), you must secure it to the wall framing. Most tubs have an integrated flange with pre-drilled holes that rests against the studs. Using a drill, drive 1-1/2 inch galvanized roofing nails or stainless steel screws through these holes into the studs. If there are no pre-drilled holes, drill them yourself about every 8-12 inches along the flange. Do not overtighten the fasteners, as this can crack the acrylic or fiberglass flange.
