Shower Regrout & Recaulk
The master shower with the hairline crack at the floor-to-wall corner that has bloomed mildew through it every other week for two winters. The guest bath tub-surround with the silicone bead at the spout that has pulled away from the tile in a quarter-inch gap. The half-bath shower with the grout color two shades darker than the day it was installed because the previous owners never sealed it and the field absorbed a decade of body oil and soap film. The big walk-in master with the niche where the sealer at the bottom shelf wore through five years ago and the cementitious grout is now half-pulverized under a thumbnail test. Shower regrout and recaulk is the Handis core restoration trade — failing cementitious grout removed mechanically down to clean tile edges, fresh sanded or unsanded grout (matched by width and product line) floated in, and 100 percent silicone replacing every change-of-plane joint where cementitious grout cracks within a year because the building moves. The work that takes a tired shower back to a finished look in one to two visits and pulls the mildew bloom out by the roots. From $700 for a single shower recaulk up to $1,800 for a master and guest combination. No licensed-plumber or licensed-electrician sub on any of it — Handis self-performs end to end.
Service
What Shower Regrout & Recaulk Includes
Shower regrout and recaulk is the standard tile-shower restoration scope — mechanical removal of failing cementitious grout in the wall and floor joints, fresh grout matched to the original joint width and color, and replacement of every change-of-plane silicone bead with fresh 100 percent silicone that flexes with the building instead of cracking like cementitious grout does. The work that buys a tile shower another decade of service without a full re-tile, and that pulls the mildew bloom out at the joint where it lives instead of bleaching the surface and watching it return.
Full Mechanical Grout Removal — Not a Surface Cover-Up
Every regrout starts with full removal of the failing grout down to clean tile edges. We use a Dremel oscillating tool with a carbide grout removal blade for tight joints (1/16 to 1/8 inch), a Roberts grout saw for wider joints, and a manual carbide grout blade for tight corners the power tool cannot reach. The joint is vacuumed clean before any fresh grout goes in — fresh grout bonded to a contaminated old joint substrate fails the same way within months. We do not skim a layer of fresh grout over an old joint, ever.
Fresh Grout Matched to Joint Width and Color
Sanded grout (Mapei Keracolor S, Custom Polyblend Sanded, Laticrete Permacolor Select) for joints 1/8 inch and wider — the standard for most shower floors and most wall fields. Unsanded grout (Mapei Keracolor U, Custom Polyblend Non-Sanded) for joints under 1/8 inch and for any natural stone where the sand would scratch. Color matched from the original product line by sample swatch — we apply the grout in a small inconspicuous joint first and let it cure 24 hours before committing to the full field, so the cured color blends with the aged field instead of standing out as a brighter line.
100 Percent Silicone at Every Change-of-Plane Joint
Cementitious grout cracks at every change-of-plane joint (floor-to-wall, wall-to-wall, curb-to-floor, edge-of-niche, around the valve trim and the showerhead arm) within a year because the building moves on those lines and rigid grout cannot absorb the movement. The TCNA standard (TCNA 04600 EJ171) specifies a flexible sealant at every change-of-plane joint. We remove old silicone or caulk at every such joint, clean the substrate, mask both sides with painter's tape, and run fresh 100 percent silicone (GE Silicone II Kitchen & Bath, DAP Kwik Seal Ultra, or Mapei Mapesil T) in a smooth, tooled bead pulled with a wet finger.
Sealer Applied After Grout Cure (Seal-Included Scope)
On the seal-included scope, two coats of a penetrating sealer (Aqua Mix Sealer's Choice Gold, TileLab SurfaceGard, or Mapei UltraCare Penetrating Plus) are applied after the fresh grout cures 24 to 72 hours. The sealer wipes onto every grout joint, soaks in for 5 to 10 minutes, and gets buffed off the tile face. The second coat applies after the first cures 24 hours. The sealer keeps grit, mop water, and cleaning chemicals from penetrating the grout pore network and extends the regrout's lifespan by about two to three years on a typical use cycle.
Honest on When Regrout Finishes the Job and When Re-tile Is the Right Call
A shower with hairline cracks in a handful of joints, failing silicone at change-of-plane joints, and a generally sound tile field is the right scope for regrout and recaulk. A shower with hollow tiles in more than 30 percent of the field, an active leak that has wet the substrate behind the tile, a failing waterproofing membrane (almost always traceable to cement-board-treated-as-waterproofing in the original install), or a substrate movement problem on the joist span is past regrout scope. We tell you on arrival and route to bathroom updates waterproofing and repair or to a full shower re-tile under bathroom updates shower and tub updates. The honest call now saves the repeat visit later.
How Shower Regrout & Recaulk Works
Seven sequential steps from arrival inspection through full mechanical grout removal, color-matched refill, change-of-plane silicone replacement, and seal cure — the sequence Handis runs on every shower regrout and recaulk project.
Inspect the Shower and Tap-Test the Tile Field
Walk the wall and floor tile with a knuckle and a coin to tap-test for hollow tiles (failed thinset bond beyond the grout failure). Press-test the substrate at the curb, the floor-to-wall corners, and behind the valve trim for soft spots. Test the existing grout with a thumbnail in a few inconspicuous joints to confirm it is structurally pulverized and not just discolored. Mark every secondary issue for the quote scope.
Mask the Shower and Pull the Sealed Hardware
Pull the showerhead arm, the valve trim plate, the shower door frame screws or the curtain rod, and any niche-shelf brackets so the silicone removal and the grout removal can reach every joint cleanly. Mask the tub or pan surface with painter's tape and a drop cloth. Run a runner from the bathroom doorway to the work area to catch grout dust as the tool walks the joint.
Remove the Failing Grout Down to Clean Tile Edges
Run a Dremel oscillating tool with a carbide grout removal blade across every joint to remove the failing grout to the tile substrate. A Roberts grout saw and a manual carbide blade reach tight corners. The joint is vacuumed clean after every wall section. Take care to avoid chipping the tile glaze on the edge — the right blade depth (about 2/3 of the joint depth) leaves the bottom 1/3 of the joint as a positioning bead so the fresh grout has a registration surface.
Remove the Old Silicone or Caulk from Change-of-Plane Joints
Pull the old silicone bead with a silicone scraper, a razor blade at a 45-degree angle, or a Goof Off silicone solvent on stubborn beads. Every floor-to-wall corner, wall-to-wall corner, curb-to-floor joint, edge-of-niche perimeter, around the valve trim, and around the showerhead arm gets the same treatment. The substrate has to be silicone-free for the fresh silicone to bond — any residue from the old bead compromises the new bond.
Mix and Float the Fresh Grout into the Wall and Floor Joints
Mix sanded grout (Mapei Keracolor S, Custom Polyblend Sanded) for joints 1/8 inch and wider, or unsanded for narrow joints, to manufacturer spec — slack consistency, no slumping when held on the float. Float the grout into every joint at a 45-degree angle to pack the joint full. Strike with a damp sponge in two passes — the first to compress the joint and pull excess off the face, the second to clean the grout line. Haze off with a soft cloth after the grout sets up.
Mask and Run Fresh 100 Percent Silicone at Every Change-of-Plane Joint
Mask both sides of every change-of-plane joint with painter's tape (1/8 inch wider than the planned bead width on each side). Run a fresh 100 percent silicone bead (GE Silicone II Kitchen & Bath in the matched color, or DAP Kwik Seal Ultra, or Mapei Mapesil T) from the corner outward. Tool the bead with a wet finger or a silicone tooling spatula to push the silicone into the joint and smooth the surface. Pull the tape immediately while the silicone is still wet. Cure 24 hours before water exposure.
Seal the Grout (Seal-Included Scope) and Final Walkthrough
After the fresh grout cures 24 to 72 hours per product spec, wipe two coats of a penetrating sealer (Aqua Mix Sealer's Choice Gold, TileLab SurfaceGard) across every grout joint. Soak 5 to 10 minutes, buff the tile face clean. Second coat after the first cures 24 hours. Walk the shower with the homeowner — show every regrouted joint, every fresh silicone bead, and the sealer coverage. Remind them no water for 24 hours after the final sealer coat.
Shower Regrout & Recaulk Pricing
Final pricing depends on shower size, wall and floor tile area, joint count, existing grout and silicone condition, and whether the project includes seal application. Color-matched grout sourcing surcharges (for discontinued grout product lines that require special-order) are passed through transparently with the line item named.

Why Handis for Shower Regrout & Recaulk
The most common shower we are asked to fix had a previous handyman regrout it with caulk instead of grout, or worse, smear a coat of latex caulk over a failing cementitious joint and hope the homeowner did not notice for ninety days. Latex caulk bonded to a wet contaminated substrate peels in weeks. Cementitious grout in a change-of-plane joint cracks in a year. Silicone applied over old silicone never bonds. There is one right way to regrout and recaulk a shower — mechanical removal down to clean tile, fresh grout matched to width and color in the flat joints, 100 percent silicone in every change-of-plane joint, sealer on the cured grout. Handis runs that exact sequence every time.
Mechanical grout removal to clean tile edges — every joint, every time
We remove failing grout with a Dremel oscillating tool and a carbide blade, a Roberts grout saw, or a manual carbide blade for tight corners. Every joint goes to about 2/3 depth so the bottom 1/3 acts as a registration bead for the fresh grout. Joints get vacuumed before refill. We do not skim, we do not surface-cover. The lifespan difference between a real regrout and a paint-on cover-up is ten years.
Color matched from the product line, sample swatch first
Aged grout is three to six shades darker than fresh grout because it has absorbed years of mop water, body oil, and cleaning chemicals. We bring the closest color from the original product line (Mapei Keracolor S, Custom Polyblend Sanded, Laticrete Permacolor Select) and run a sample swatch in an inconspicuous joint before committing to the full pour. The swatch cures 24 hours so we can confirm the new grout will blend with the aged field at cured color, not stand out as a brighter line.
100 percent silicone, not caulk, at every change-of-plane joint
The TCNA EJ171 standard specifies a flexible sealant at every change-of-plane joint. We use 100 percent silicone (GE Silicone II Kitchen & Bath, DAP Kwik Seal Ultra, Mapei Mapesil T) because latex caulk fails in a wet environment within a year. The bead is masked with painter's tape on both sides, tooled with a wet finger, and the tape is pulled while the silicone is still wet. The result is a precise straight bead that flexes with the building and seals the joint against water intrusion.
Sealer on every fresh grout joint when seal is in scope
The seal-included scope wipes two coats of penetrating sealer (Aqua Mix Sealer's Choice Gold, TileLab SurfaceGard) across every fresh grout joint after the grout cures 24 to 72 hours. The sealer keeps mop water, body oil, and cleaning chemicals from penetrating the grout pore network and extends the regrout lifespan by two to three years. Owners who skip the seal step on the regrout will be calling for color sealing inside five years; the seal step now is the cheaper path.
Honest on when regrout finishes the job and when re-tile is the right call
A shower with sound tile and failing grout is the right scope for regrout and recaulk. A shower with more than 30 percent hollow tiles, an active leak, a failing waterproofing membrane (the 1990s cement-board-as-waterproofing failure mode), or a substrate movement problem on the joist span is past regrout scope. We tell you on arrival and route to bathroom updates waterproofing and repair or a full shower re-tile. We do not pretend a regrout will fix a substrate problem.

Customer Reviews
Recent shower regrout and recaulk reviews from verified Handis customers.
Master shower regrout and recaulk after a previous handyman had smeared latex caulk over the failing grout at the floor-to-wall corners. Handis pulled all the old caulk and old grout, refilled the field joints with sanded grout matched to the original color, and ran fresh GE Silicone II at every change-of-plane joint. The silicone bead is the tightest, straightest bead I have ever seen on a shower. Two years and counting, no mildew bloom anywhere.
Guest bath tub-surround recaulk. The silicone bead at the spout had pulled away in a quarter-inch gap and the floor-to-wall corner was bloomed with mildew. Tech masked everything with painter's tape, ran fresh silicone at every joint, pulled the tape clean. The bead is straight, the mildew is gone, water is not getting behind the spout flange anymore. Two-hour visit, perfect outcome.
Whole-shower regrout, recaulk, and seal in our master. The grout had darkened over fifteen years and was pulverizing under a thumbnail in a few joints. Handis spent an afternoon removing the old grout with a Dremel and a grout saw, refilled the next morning, ran silicone after the grout cured, came back two days later to apply the sealer. The shower reads brand new and water beads off the grout now.
Master and guest shower combination project. They split it across two visits to let the master cure before they did the guest. Both showers had the same failure pattern (failed silicone at the floor-to-wall corners, mildew bloom at the curb) and both came back to a finished look. The color match on both grout pours is invisible against the aged field.
Tub-shower combo regrout and recaulk in our guest bath. The grout at the spout was failing and the silicone bead at the tub-to-tile joint had pulled away in a long line. Handis took the spout off, pulled the trim, did the full regrout and recaulk, set the spout back on a new escutcheon. The bath came back to service the next day and looks crisp.
