The Pan Beneath the Tile
Liners, membranes, mud beds — the layer your shower stands on.
Under every tile shower floor sits the pan: a sloped bed plus a waterproof liner or membrane that catches what grout lets through. When Berlin showers leak into ceilings below, the pan has failed — torn liner, flat spots, clogged weep holes, or a 1970s lead pan giving up. A pan rebuild replaces that hidden layer properly: pre-slope, liner or bonded membrane, sloped setting bed, flood-tested before tile. It's the difference between a floor that lasts five years and one that lasts thirty.
- Flood-tested diagnosis. Plug, fill, mark, wait — proof of pan integrity or failure.
- Two proven systems. Liner + mud bed (classic) or foam tray + membrane (modern).
- True pre-slope. Water reaches weep holes instead of sitting under tile.
- Clamped drains. Membrane mechanically locked at the drain, never just cut around.
- Photo + test record. You see the pan and the test results before tile covers them.
Pans that hold in Berlin

Spa texture, expert grout.
Modern lines that turn slope.
Berlin notes
Berlin's most common call: a fiberglass surround gone yellow and chalky around a perfectly good tub — re-tile the walls, keep the tub. In Berlin we flood-test free whenever ceilings below show staining: Kensington's older baths still run the original 4x4 wall tile over plaster, usually with a failing caulk line at the tub. The ranch baths are fiberglass tubs with surround panels yellowed at the seams — the classic re-tile trigger. A sound pan saves you $500–$1,000 — we prove soundness instead of assuming failure.
Common questions
We plug the drain, fill the pan two inches, mark the level and wait — typically 24 hours for diagnosis, shorter for post-build verification. Any drop means pan failure, located and shown.
Both, matched to the job: liner-and-mud for custom shapes and maximum durability feel; foam tray + sheet membrane for speed and precision slope. Same warranty either way.
Intermittent staining usually means pan or wall-joint failure (shower-use correlated); constant damp means supply plumbing. Our diagnosis separates them free — different trades, different bills.
Keeping sound walls saves 60–70% versus full rebuild. A floor+pan job at $1,500–$2,800 replaces a $6,000–$12,000 gut when walls qualify.
