The 11 Best Bathroom Renovation Contractors in New York

KBR suits apartment owners who want designers and builders under one contract rather than a chain of subcontractors. Its showroom on West 28th Street is the base for in-house designers, foremen and coordinators, and the firm works in co-ops, condos, pre-war apartments and brownstones. A free 30-minute call produces a cost estimate and timeframe, with a Zoom call or an in-home measure as alternatives. A downloadable pricing guide helps set a realistic budget early.

Renaissance General Contracting suits Brooklyn brownstone owners whose bathroom is part of a bigger job. Based on Smith Street, the firm handles kitchen and bathroom remodels, gut renovations, structural upgrades and historic restoration. Estimates break down labor, materials, finishes and DOB filings, with a cost and timeline breakdown. It also coordinates architects, engineers, permits and inspections, which saves owners from managing several trades at once.

Home Design & Co suits Upper East and Upper West Side apartment owners dealing with demanding co-op boards. Founder and general contractor John Posada runs the family-owned firm from East 23rd Street, and it carries $5 million in insurance to meet building requirements. The team prepares board packages, insurance certificates and Department of Buildings filings, and plans elevator bookings and debris removal around building hours. Clients receive a 3D design and an itemized estimate before work begins.

Brener Construction is a good fit for apartment owners who expect regular updates while they are away from the job. The locally owned company, with more than 20 years in the trade, handles bathroom updates, kitchens and gut renovations, including the plumbing, electrical, flooring and millwork they involve. It has offices in Midtown Manhattan and in Oakland Gardens, Queens. Its guides explain DOB permits and co-op and condo alteration agreements, useful reading before approaching a board.

The general contractor pairs every project with an in-house interior designer and a dedicated project manager, and clients track schedules, photos, budgets and messages through its Renotech portal. It works in co-ops, condos and townhomes, and coordinates the independent architects and engineers that building approvals often require. Every detail is approved before construction starts, which limits surprises once the bathroom is open.
