Make Your Bathroom a Space to Enjoy


We’ll Turn Your Ideas into a Reality

The average person spends over 800 days of their life in the bathroom. That is why we believe it is so important to make it a space that is clean, fresh, and relaxing. With spa tubs and steam showers and many other luxury options, we can curate an exquisite space to help you show up in your life as the best version of yourself.

Low VOC


Volatile organic compounds (VOCs) are harmful chemicals  that are released from certain products or processes.  At Maingreen Remodel & Construction, we use products and practices to eliminate VOCs and create a safe environment for you and your loved ones.

Low-flow plumbing


Low flow plumbing fixtures reduce and limit the amount of water released per minute. It is a way for you to save money and help the environment.

Choose Natural Light


One of our top considerations is how to  bring more natural light into your space. It saves money, increases comfort, benefits houseplants, reduces stress and anxiety levels, promotes better sleep, and increases your home’s value.

Renewable Energy


There are several creative ways to introduce renewable energy into your home. Renewable energy is sourced from natural, organic elements such as sun, wind, and water. Call us today for a free assessment.

What a bathroom renovation in Los Angeles includes

A full bathroom remodel replaces what you see and what sits behind it. In the order the work happens:

  1. Demolition of the old tile, tub or shower, vanity and toilet, and a check of the wood and drywall behind them for water damage and mold.
  2. Plumbing: the shower valve, supply lines and drains set for the new layout.
  3. Electrical: lighting, outlets and the exhaust fan.
  4. Waterproofing of the shower floor and walls before any tile goes on.
  5. Tile, vanity and fixtures: floor and wall tile, the vanity and sink, the toilet, shower glass and paint.

Plumbing and wiring are inspected by the city before the walls are closed, so the order matters. We apply for all the permits your home improvement project requires well before construction.

Tub, walk-in shower or both?

In most bathrooms this is the main layout decision, and it sets much of the plumbing work:

  • Tub to walk-in shower

    The tub comes out and a tiled shower with glass takes its place. It opens up the room and makes stepping in easier; a bench or a niche can be built in.

  • New tub and shower combination

    One fixture for bathing and showering. A practical choice when it is the only bathroom in the house or there are small children.

  • Separate tub and shower

    A spa tub or a soaking tub beside a separate shower. It needs more floor space, so it usually goes with a larger primary bathroom or a layout change.

Tub to shower conversion for seniors

A tub to shower conversion takes out the bathtub and builds a tiled walk-in shower with glass in its place, so a parent who can no longer step over the tub wall walks in instead, and a seat can be built into the tile. We do it as a licensed contractor (License #1093329), you see the new shower in a 2D or 3D design before work starts, and we offer senior, veteran, military and teacher discounts. Within 24-48 hours of your call, one of our team members will visit your home to scope out your space.

For an older parent, settle these in the design:

  • The entry: a low curb, or no curb where the floor can be sloped to the drain, so there is no wall to step over.
  • A seat and a niche built into the tile, with the niche within reach of the seat.
  • A handheld shower on a slide bar, so showering seated works.
  • Grab bars: the CDC, which names falls the leading cause of injury for adults 65 and older, advises grab bars inside and outside the tub or shower and next to the toilet. Raise them with whoever draws the design.

A contract signed by a parent 65 or older

California gives a buyer 65 or older a Five-Day Right to Cancel a home improvement contract instead of three days, unless it was negotiated at the contractor's place of business (repair work after a declared emergency gets a Seven-Day Right to Cancel instead): written notice by midnight of the fifth business day after receiving a signed and dated copy of the contract (Business and Professions Code 7159). Check the license on the CSLB license check first; the payment rules are in what to check before you hire a remodeling contractor, and you can ask about financing through our financing partners.

Lighting, fans and water use: California rules

Bathroom lighting you add or replace falls under California's Energy Code (Title 24, Part 6, Section 150.0(k)), which in the 2025 edition applies to projects whose permit application is made on or after January 1, 2026:

  • At least one light in the bathroom is controlled by an occupancy or vacancy sensor that turns it off automatically.
  • A light built into the exhaust fan is switched separately from the fan.
  • New fixtures and lamps are certified high-efficacy (JA8) light sources, in practice LED; lighting built into the exhaust fan or a vanity mirror is an exception.

In a house built and available for use on or before January 1, 1994, California Civil Code 1101.4 makes the final permit approval of an alteration conditional on replacing noncompliant plumbing fixtures with water-conserving ones: a toilet that uses more than 1.6 gallons per flush, a showerhead over 2.5 gallons per minute or an interior faucet over 2.2 gallons per minute (Civil Code 1101.4).

For water, look for the WaterSense label on showerheads, faucets and toilets: the EPA requires labeled products to be independently certified for both water use and performance (EPA WaterSense).

Warning signs behind the tile

  • Loose or cracked tiles, or grout that keeps cracking in the shower: water may be getting behind them.
  • A soft or bouncy floor around the toilet or tub.
  • Peeling paint or dark spots on the ceiling: moisture is not leaving the room. The EPA calls moisture control the key to mold control.
  • A musty smell that cleaning does not remove.
  • Slow drains or low pressure at every fixture, which point to the plumbing rather than the fixtures.

When demolition finds mold, mold remediation becomes part of the same remodel. A bathroom can also be one part of a whole-home remodel.

What sets the price of a bathroom remodel

  • Layout: moving the toilet, the shower drain or the vanity means new drain and supply lines.
  • The shower: a tub-to-shower conversion, the size of the tiled area and the glass.
  • Tile and fixtures: the material and size of the tile, the vanity, faucets and the toilet.
  • Electrical and ventilation: new lighting, outlets or an exhaust fan ducted outdoors.
  • What demolition finds: rotted subfloor, water damage or mold behind the old shower.

The estimate is free, and you can ask about financing through our financing partners.

Bathroom remodeling questions

Can you turn my bathtub into a walk-in shower?

Yes. The tub comes out, the drain and valve are set for the shower, the floor and walls are waterproofed and tiled, and the glass goes on last. You see the new shower in a 2D or 3D design before work starts.

Do I need a permit for a bathroom remodel in Los Angeles?

Usually yes. Inside the City of Los Angeles, LADBS offers a combined online permit for a bathroom remodel in a house or duplex that keeps the same layout: tile, wall finishes, flooring and plumbing and electrical fixtures. Moving fixtures into new spots or changing walls goes through plan check, and condominium buildings do not qualify for the online permit. We apply for all the permits your home improvement project requires well before construction.

Do you do the plumbing and electrical work too?

Yes. Plumbing and electric are part of our bathroom remodels, along with tubs and tiles, vanity and sink installs and reinventing the space.

Do you design the bathroom too, and how long does a remodel take?

Yes. Depending on your needs and aesthetics, we choose one of our designers to create a 2D or 3D rendering of your space. You work with them to choose details and materials that match your aesthetic, and we never start construction until you approve of the design. We offer 2D and 3D designs and a free backsplash when you remodel your bathroom with us.

How long it takes depends on the job, and your contract has to say it: California requires a home improvement contract to state an approximate start date and an approximate completion date (Business and Professions Code 7159). A layout change goes through plan check instead of the online permit inside the City of Los Angeles (see the permit question above), and what demolition finds behind the old shower can add work.

What if there is mold behind the shower wall?

It is removed and the cause is fixed as part of the same job: we also do mold remediation, so the wall is rebuilt only once it is clean and dry.

Which areas do you serve for bathroom remodeling?

Los Angeles and nearby cities, including Burbank, Glendale, Pasadena, Culver City, Inglewood, Torrance, Long Beach, Whittier, Norwalk, Santa Clarita, Palmdale and Lancaster.
