Small errors compound. A half-inch off center can misalign supply lines, collide with a drawer box, or leave trim plates revealing unglazed tile. Cross-check diagonals, confirm rough-in heights, and mark centerlines on painter's tape before committing to cuts, cores, or anchors.

Fixtures live in motion. Check door, shower screen, and cabinet swing paths, allow aerator access, and plan wrench clearance for future cartridge swaps. Print templates or make cardboard mockups; they prevent collisions that only appear once handles, spouts, and stop valves actually move.

Dry-fit fasteners, escutcheons, and traps before sealing anything. This reveals misaligned holes, wall bow, or insufficient tailpiece length while adjustments remain painless. Photograph positions, label shims, and verify reach with the largest user's hands, not only your own, before final tightening.

Plumber's putty excels under flanges on non-stone surfaces, remaining pliable for service, but it stains porous marble or granite. Neutral-cure silicone bonds to many materials, resists mildew, and seals permanently. Match material, exposure, and serviceability rather than reaching reflexively for one familiar tub.

Do not tape compression fittings; the ferrule creates the seal. Apply PTFE tape clockwise on tapered threads only, two to three wraps, then a compatible pipe dope if specified. Wipe excess, orient outlets, and recheck after pressurizing because first impressions and drips often disagree.

Movement cracks brittle joints. Bridge dissimilar materials with flexible sealant, not grout, and tool smooth to shed water. Backer rod controls depth for better elasticity. Before sealing, remove dust with alcohol, dry completely, and tape edges for crisp lines that last years.
