— The Truth —
The tile is outdated. The tub nobody uses is taking up half the room. Every morning starts in a bathroom that hasn't changed in fifteen years — and you already know it's time.
The problem isn't knowing what you want. It's finding someone you actually trust to do it right.
That's where Lumii comes in.
— Our Work —






Every project above was completed by our local NJ crew. Real homes. Real results. No stock photos.
— Our Services —
Replace your old tub with a custom walk-in shower. Clean lines, modern tile, zero wasted space.
Starting at $5,000Top to bottom — new tile, new fixtures, new layout if needed. We handle demo, plumbing, electrical, and every finish. Done right.
Heated floors. Freestanding soaking tub. Frameless glass shower. Body sprays. If you've been imagining it, we've built it.
From $15,000Own an investment property in NJ? A bathroom renovation can increase your rent by $150–$300 per month. We work with landlords on efficient, tenant-ready upgrades that pay for themselves.
— How It Works —
We come to you. Measure the space, hear your vision, and give you honest pricing upfront. No sales pressure, no guessing.
You get a detailed scope — what we're doing, what it costs, how long it takes. Everything in writing before anything starts.
Our crew shows up. Demo, plumbing, tile, fixtures, cleanup — all of it. You don't have to manage a thing.
That's it. No surprises. No leftover mess. Just a space you're genuinely proud of.
— Why Lumii —
Lumii is a New Jersey company. The people building your bathroom live and work in the same communities you do. You'll meet the crew — not a dispatcher two states away.
Five years of hands-on residential construction. We've seen every NJ home challenge — old plumbing, tight spaces, odd layouts. We know how to handle what other contractors walk away from.
Fully licensed and insured in New Jersey. We pull permits when required and do the work by the book.
Don't let budget hold you back. Ask about our financing options — get the bathroom you want now, pay over time.
Your home is not a construction zone to us. We protect your floors, contain the dust, and clean up before we leave each day. Your life keeps moving while we work.
— For Property Investors —
An outdated bathroom is costing you money every month.
In Northern NJ, a renovated bathroom can increase your rent by $150–$300 per month. On a $10,000 remodel, that's a full return on investment in under 3 years — plus higher tenant quality and faster vacancy fill.
We've worked with NJ landlords and investors on efficient, high-quality renovations designed to maximize rental income without over-improving the unit.
— Testimonials —
"Honestly, I wish we'd done this five years ago. We had the same ugly bathroom since we moved in — cracked grout, that awful builder-grade tub. Jay and his crew came in, kept everything clean, and now I literally just stand in my new shower smiling every morning. My sister came over and said it looks like a hotel. Best money we've spent on this house."
"I manage three rental units in Jersey City and one in Hackensack. Had Lumii do the Hackensack unit first — they finished in under two weeks, came in right at the quote, and the place looks brand new. Listed it at $200 more a month and had a tenant signed within a week. Already scheduled them for my next unit."
"What sold me was the estimate — Jay came to the house, spent a real hour with us talking through options, and never once tried to upsell us on stuff we didn't need. The crew showed up on time every single day and cleaned up before they left. Our master bath went from embarrassing to the nicest room in the house. Can't say enough good things."
