Overview
Tile And Waterproofing Done Right
Tile is what you see in a bathroom, but the layers behind it decide how long it lasts. In a shower, grout and tile shed most of the water, yet some always passes through; the membrane or pan underneath is what keeps it out of the framing.
Floors need their own preparation. A floor that flexes too much will crack tile and grout, so a remodeler should check the subfloor and use an underlayment suited to the tile size before setting anything.

Signs Your Bathroom Tile Needs Attention
Cracked Or Hollow Tiles
Tiles that crack or sound hollow when tapped can mean the bond has failed or the floor is moving. Replacing one tile rarely fixes the cause.
Grout That Keeps Crumbling
Grout that washes out or cracks again soon after repair often points to movement or moisture behind the surface.
Stains On The Ceiling Below
A water stain under a shower can come from failed waterproofing, a pan leak or a plumbing problem. A remodeler and a plumber can help pinpoint which.
Mold Along Joints And Corners
Persistent mildew in corners and along the tub line may mean the caulk has failed or the wall stays wet. Inside corners and changes of plane should get a flexible sealant, not hard grout.
Worn Or Dated Floors
Old sheet vinyl, chipped tile or discolored grout make a bathroom feel tired. New tile can refresh the room without moving fixtures.

Before You Get Tile Estimates
These steps help you get accurate tile quotes you can compare.
Stop Using A Leaking Shower
If water is showing up below a shower, stop using it until someone can look. Continued use spreads damage into framing and ceilings.
Measure Floors And Walls
Note the floor area, the shower wall height and width, and any niches or benches you want. This lets remodelers estimate tile quantity and labor.
Choose A Tile Type Early
Settle on the general direction: porcelain, ceramic, natural stone, mosaic or large-format. Material affects prep, cutting time and the setting products a pro will use.
List What Matters To You
Slip resistance, easy cleaning, heated floors, a niche, or a pattern like herringbone all change the job. Put them on paper before the first visit.
Verify Registration And Ask About Permits
Check a remodeler's Home Improvement Contractor registration online, and ask the building department whether your tile job needs a permit, especially if plumbing changes too.
What to expect
What A Tile Pro Will Check
Expect the remodeler to inspect the subfloor and walls before quoting. They'll look for soft spots, flex and old water damage, and whether existing drywall in the shower area has to come out, since ordinary drywall doesn't belong behind shower tile.
A clear proposal names the waterproofing method, the backer board or membrane, a setting mortar suited to the tile, the grout type and where movement joints will go. Large-format tile needs a very flat surface, so leveling work may be part of the price.
If plumbing changes are needed, such as a new drain or valve, a plumber with a Massachusetts license handles that under a plumbing permit before tile goes on. A flood test of the shower pan before tiling is worth asking about.
Hire smart
Hiring A Bathroom Tile Installer
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.
Ask About HIC Registration
Mass.gov lists installers of wall and floor coverings among the trades that may not need HIC registration, so ask what the full scope covers. For a shower rebuild or wider remodel, hiring a registered contractor keeps your access to state arbitration and the Guaranty Fund.
Ask About Waterproofing Methods
Ask which membrane system they use, how they treat seams and corners, and whether they flood-test pans. Their answers tell you a lot about their approach.
Get A Detailed Written Estimate
Ask for line items for demolition, prep, waterproofing, tile labor, materials and grout. Confirm who supplies the tile and how extra for cuts and breakage is handled.
See Their Finished Work
Ask for photos of recent tile jobs and references you can call. Look closely at grout lines, cuts around fixtures and how edges are finished.
Costs
What Affects The Cost Of Bathroom Tile Installation
Surface preparation is often the hidden cost. Removing old tile, repairing subfloor, leveling for large tiles and installing a new shower pan and membrane all take time before the first tile goes down.
Tile choice and layout matter as well. Small mosaics, natural stone, intricate patterns and lots of cuts around niches and benches take longer to install than plain porcelain laid straight. Ask remodelers to quote the same tile and pattern so their estimates line up.
Across the region
Bathroom Tile Across The South Shore
Local water chemistry affects how grout and tile hold up to cleaning. Pembroke's 2025 water quality report found iron up to 753 ppb and manganese up to 197 ppb, both above their secondary limits, and those minerals can discolor light grout over time. Rockland's supplier, the Abington and Rockland Joint Water Works, reported total hardness of 53 to 79.3 ppm in 2025, so ask a remodeler about grout colors and sealers that suit your town's water.

Bathroom Tile Installation Questions
Still not sure? Send a short request and a local pro can answer the specifics.
Does bathroom tile installation need a permit on the South Shore?
Tile alone often doesn't, but work that changes plumbing, electrical or structure usually does. Rules vary by town, so check with your local building department before work begins.
What's the difference between grout and waterproofing?
Grout fills the joints between tiles but isn't waterproof on its own. A membrane or pan beneath the tile is what keeps water out of the walls and floor.
Can new tile go over old tile in a Canton or Quincy bathroom?
Sometimes on floors, if the old tile is firmly stuck down and flat and the added height works at doors and fixtures. In showers, removing old tile is the safer route because it lets the remodeler check and replace the waterproofing.
How do I keep grout clean if my Pembroke home has iron in the water?
Darker grout or an epoxy grout hides mineral staining better than light cement grout, and a squeegee after each shower helps. Ask your remodeler about grout and sealer choices that suit your water.
Which tile is easiest to maintain in a bathroom?
Porcelain is dense and absorbs very little water, which makes it a common choice for floors and showers. Natural stone needs periodic sealing, and smaller tiles mean more grout to clean.
