A space-efficient Park Slope bathroom remodel with a walk-in shower, warm oak storage, updated systems, and a clear NYC cost and timeline breakdown.
Get Your Free On-Site EstimateA full Park Slope bathroom renovation typically costs $30,000–$65,000+ and takes about 4–6 weeks of construction once building approvals and materials are ready. The main cost drivers are plumbing changes, waterproofing, tile complexity, custom storage, and conditions uncovered behind pre-war walls.
The Project
A Modern Bathroom That Works in a Brooklyn Brownstone
The goal was simple: make a compact Park Slope bathroom feel calmer, brighter, and easier to use without wasting space. The design replaces visual clutter with a frameless walk-in shower, a floating oak vanity, a recessed medicine cabinet, and warm neutral finishes that suit a pre-war home without trying to imitate its age.
For New York homeowners, the important work is behind the finishes. Plumbing and electrical routes must fit the existing building, wet areas need a complete waterproofing system, and deliveries, debris removal, and water shutoffs have to follow building rules. Planning those details before demolition keeps the visible result clean and the schedule realistic.

Cost & Timeline
Realistic Planning Numbers for Park Slope
| Scope | Typical planning range | Construction time |
|---|---|---|
| Same-layout full renovation | $30,000–$45,000 | About 3–5 weeks |
| Modern renovation with custom storage or premium tile | $45,000–$65,000 | About 4–6 weeks |
| Layout or major plumbing changes | $65,000+ | About 6+ weeks |
These are current NYC planning ranges, not a claim about the private invoice for this project. Board review, permits, and material lead times can add several weeks before construction begins. Older brownstones should also carry a 10–15% contingency for hidden plumbing, subfloor, or framing conditions.

Park Slope Planning
What Homeowners Should Confirm Before Starting
Ask whether the quote includes protection, debris handling, waterproofing, plumbing trim, shower glass, permits, and final cleaning. If the home is in a co-op or condo, approval is separate from NYC permitting. If it is a brownstone in the Park Slope Historic District, interior work usually does not require LPC review unless the project affects protected exterior elements.
For accurate numbers, the contractor needs to inspect the bathroom and the systems serving it. Learn more about our NYC bathroom renovation service, explore our Park Slope contracting services, or request a free on-site estimate.
Frequently Asked Questions
Renovation Project FAQs
How much does a bathroom renovation cost in Park Slope?
A full Park Slope bathroom renovation typically costs $30,000–$65,000+, depending on plumbing changes, waterproofing, tile complexity, custom storage, finish level, and hidden pre-war conditions. An on-site assessment is required for an exact estimate.
How long does a full bathroom remodel take?
Construction typically takes about 4–6 weeks after building approval, permits, and materials are ready. Layout changes, custom glass, concealed damage, or building restrictions can extend the schedule.
Do I need permits or building approval in Park Slope?
Plumbing, electrical, or layout changes may require NYC permits, and co-op or condo buildings usually require an alteration package. Interior work generally does not require LPC approval unless it affects protected exterior elements.
Can I stay home during the renovation?
Staying home can be practical when another bathroom is available and the work zone can be isolated. In a one-bathroom home, temporary accommodation is usually more comfortable because of noise, dust, and planned water shutoffs.
What should a complete bathroom renovation estimate include?
A clear estimate should identify protection, demolition, debris removal, licensed plumbing and electrical work, waterproofing, tile, fixtures, vanity, shower glass, paint, permits where required, final cleaning, and close-out.
