Jersey Shore bathrooms
A shore bathroom is built around water and salt air: tile set in mortar, cement board in place of paper-faced drywall, and metal that holds up near the ocean. In Cape May County, 50%12 of homes are vacation or other seasonal homes by the Census count, so many of these bathrooms belong to beach houses.

What defines the look
- Tile set in mortar
- FEMA's flood-materials bulletin rates ceramic and porcelain tile acceptable for floors and walls below the flood elevation only when set in mortar; tile set with organic adhesive is not acceptable.3
- Stone with waterproof grout
- FEMA rates natural stone acceptable for floors and walls below the flood elevation when it is a non-absorbent solid or veneer set with waterproof grout.3
- Cement board behind the walls
- FEMA rates cement board and fiber-cement board acceptable for walls below the flood elevation, while paper-faced gypsum board is not acceptable for walls or ceilings.3
- Vinyl or tile underfoot, not wood
- FEMA rates homogeneous vinyl tile or sheet vinyl laid with chemical-set adhesives acceptable for floors below the flood elevation, but not vinyl over plywood, solid or engineered wood flooring, or carpet.3


- Nothing finished under a raised house
- Middletown Township says enclosed areas below the base flood elevation may not be finished or used as living space, are limited to storage and vehicle parking, and may not contain plumbing fixtures, appliances, heating and air-conditioning equipment or ductwork.4
- Metal that stands up to salt air
- FEMA's coastal construction guide says metal corrosion is most pronounced on homes within 3,000 feet of the ocean and advises hot-dipped galvanized or stainless steel hardware.5
- A fan that vents outdoors
- The 2021 International Residential Code requires bathroom exhaust to go directly outdoors, never into an attic or crawl space, with fan capacity of 50 cfm run intermittently or 20 cfm run continuously.6
Before you start at the shore
Find out where the flood line sits on your lot before choosing any finishes. FEMA defines flood damage-resistant materials as products that can withstand direct and prolonged contact with floodwater, meaning at least 72 hours, and requires building materials below the base flood elevation in a special flood hazard area to be flood damage-resistant.3 In a house that has already been raised, that line usually falls below the living floor, and the space underneath is held to a stricter standard than the rooms above it.
A big bathroom job can count toward a flood rule that reaches the whole house. Ocean City counts interior finishes, bathroom tile and fixtures, kitchen and bathroom cabinets, plumbing and built-in kitchen appliances toward its 50 percent flood-improvement test, but not plans, surveys or permit fees.7 In Ocean City, if repairs and upgrades exceed 50 percent of the home's value, the owner must bring the home into compliance with the city's Flood Damage Prevention Ordinance, which could include raising it.7 Long Beach Township runs a similar test with a different yardstick. Long Beach Township says work that equals or exceeds 50 percent of a building's replacement cost, as set by the tax assessor, means the entire structure must meet FEMA's flood rules, which could require raising it so the first floor is one foot above the base flood elevation.8 Ask your town's construction office how it adds up the cost before the design is final.
Plumbing near the ocean has its own wear problem. FEMA advises against joining dissimilar metals near the coast, especially pairs with high galvanic potential such as copper and steel.5 When new supply lines meet older pipe, ask the company how the connections will be kept apart and protected.
Where these bathrooms are
Census counts show how much of the Jersey Shore is vacation housing. In Cape May County, 50%12 of all homes are held for seasonal, recreational or occasional use, against 3%12 across New Jersey. Bathroom remodeling in South Jersey
Ocean County's shore runs from Long Beach Island up to Point Pleasant Beach, and 13%12 of the county's homes fall in that seasonal group. Shore towns follow the same building code as every other town in the state. New Jersey's construction code is the same statewide, with no separate local requirements; municipally employed, state-licensed construction officials and inspectors enforce it, and the owner or the owner's agent, such as the contractor, is responsible for getting the permits.9 Bathroom remodeling in Central Jersey
