Sharon · Tile And Waterproofing
Retiling a shower, floor, or basement bath in Sharon? See how the town's well water and wet spots affect tile choices, then reach an independent local remodeler who serves Sharon.
Sharon, Massachusetts
Tile in a Sharon bathroom has to live with Sharon's water. The town draws its supply from its own groundwater wells, and its water reports describe iron and manganese in some of them, along with calcium and sodium in the supply. Those minerals are the usual culprits when light grout turns orange or brown around a drain, or when glass and tile pick up a cloudy film.
The town is building a treatment plant at Well Station 4 on Tree Lane to remove PFAS from three wells and iron and manganese from two of them. As of its project page, the town expected construction to finish in fall 2026 and the plant to be fully on line for summer 2027. Until then, and for anyone sensitive to staining, grout color and sealing choices are worth a conversation with your installer.
This site never sets tile itself. It connects Sharon homeowners with independent remodelers and tile setters who serve the town, and shares guidance to help you compare their approaches.
Rusty or brown stains around the drain often come from minerals in the water combined with porous grout. Regrouting with a denser product may help, but persistent staining can also signal water getting behind the tile.
A crack running across several tiles usually points to movement in the floor or wall beneath, not just the tile.
Dampness under floor tile in a lower-level bathroom can feed mold. Have the source of the moisture found before retiling.
Tile that taps hollow has lost its bond. In a shower, that's a sign water may already be in the wall.
Local knowledge
What comes out of the tap and what sits under the house both affect how a tile job holds up.
Iron And Manganese
The water treatment plant project at Well Station 4 targets iron and manganese in wells 2 and 3, along with PFAS. Ask your installer about darker or stain-resistant grout until the plant is running, and about sealers that make deposits easier to clean.

Minerals In The Supply
Supply samples in 2025 showed calcium up to 39.4 ppm and sodium up to 112 ppm, and the report notes Well 6 has elevated manganese and is used rarely. Smooth, low-texture tile and well-sealed grout lines shed mineral film more easily than rough stone.

Known Flood Spots
The town's hazard mitigation plan update lists flooding areas including Billings Street, Morse Street, and Main Street near Massapoag Brook. If you're tiling a basement bathroom in an area like these, choose tile, setting materials, and a membrane that tolerate dampness.
Right now
Sort out water and moisture questions before choosing tile.
Photograph staining around drains, fixtures, and grout lines. It helps the installer judge whether water chemistry or a leak is the cause.
If the bathroom is on the ground floor or in a basement, watch for damp spots after heavy rain and share what you see.
Bring samples into the bathroom and look at them in your own light. Matte and textured tiles look and clean differently than glossy ones.
Tile isn't waterproof by itself. Ask each installer which backer board and membrane they plan to use.
What to expect
An installer will check the floor for flex and the walls for flatness, then explain the substrate and waterproofing system. In a shower, expect a membrane or a sealed backer board behind the tile and a sloped, waterproofed pan, often flood-tested before tile goes down.
Tile alone usually doesn't need a permit, but tile work is often part of a remodel that does. If the shower valve or drain changes, the plumber files with Sharon's Building Division and the rough plumbing is inspected before the walls are closed.
Grout needs time to cure before regular use, and some sealers require waiting days before the first shower. Ask your installer for a care schedule that fits Sharon's water, including how often to reseal.
Hire smart
In Massachusetts, contractors who remodel an existing owner-occupied home of one to four units must be registered Home Improvement Contractors, and the plumbing and electrical parts of the job must be done by a plumber and an electrician who hold Massachusetts licenses, under permits.
A clear answer, naming the membrane or system, suggests the installer understands what keeps water out of the wall.
Ask about grout types, colors, and sealers that resist staining from iron, manganese, and mineral deposits.
If the tile work is part of a home improvement project, the contractor should be a registered Home Improvement Contractor. Check on the state's lookup.
Photos or addresses of finished showers show the installer's layout skills, especially at corners, niches, and drains.
Costs
Prep often outweighs the tile itself. Removing old mortar-bed tile, leveling floors, and installing a full waterproofing system all take time, and basement bathrooms in damp areas may need extra moisture control.
Tile size, material, and pattern matter too. Large-format tile needs flatter substrates, and intricate patterns add cutting time. Ask for an itemized written estimate that lists demolition, prep, waterproofing, tile, grout, and sealer, so you can compare bids that cover the same layers.

Iron and manganese in the water can stain porous grout, and the town is building a plant to remove them from two of its wells. A denser grout, a darker color, or a good sealer can help, but have a remodeler rule out a leak behind the tile too.
The town expects the plant to remove iron and manganese from wells 2 and 3 once it's fully on line, which it planned for summer 2027. Ask your installer about grout choices that work before and after the change.
Yes, with the right materials. Choose tile and setting products that tolerate moisture, install a membrane, and fix any water entry before tile goes down.
Tile on its own generally doesn't, but changes to plumbing, framing, or wiring as part of the job do. Those permits go through Sharon's Building Division.
