Bathroom remodel ideas sorted from surface work to layout changes: what each one involves, which save water, and which bring permits and lead rules.

Good bathroom remodel ideas start with one question: what does the idea touch? Paint, grout and a reglazed tub change surfaces. A new faucet or toilet on the same connections changes fixtures. Moving a drain, a wall or a circuit changes the layout. Those are the ideas to check with your building department about a permit. This guide sorts the common ideas into those three groups so you can see what each one really involves.

- **Sort each idea by what it touches:** surfaces, fixtures on their existing connections, or the layout. Then get each one priced on its own.
- **WaterSense fixtures cut water use:** showerheads use no more than 2.0 gallons a minute, bathroom faucets 1.5, toilets 1.28 gallons a flush.
- **Falls caused 81.1% of the nonfatal bathroom injuries** treated in US emergency departments in 2008, and injury rates were highest in or around the tub or shower.
- **Pre-1978 home?** A contractor paid to disturb more than six square feet of paint in a room, or to demolish painted surfaces of any size, must be certified for lead-safe work.
- **Get every idea priced in writing** from more than one contractor before you settle on it.

## How to sort bathroom remodel ideas by scope

Most lists of bathroom remodel ideas mix a new towel bar with a moved shower as if they were the same kind of decision. They aren't. Sort them by what they touch:

| Group | Typical ideas | What it touches |
| --- | --- | --- |
| Surfaces | Regrout, reglaze the tub, paint or an accent wall, new floor tile, new mirror and hardware, open shelves | No plumbing or electrical work |
| Fixtures in place | New showerhead, faucet, toilet, vanity on the same connections, a light fixture on the existing wiring, a better exhaust fan | Existing plumbing and wiring connections, left where they are |
| Layout | Tub to shower, moved toilet or drain, new walls, a recessed shower niche, heated floors, added lighting circuits | New plumbing, wiring or framing; ask your building department about a permit |

The [cost guide](https://bathbudget.com/bathroom-remodel/bathroom-remodel-cost) breaks the price down by these same scope levels. If you want your own numbers for the ideas you're weighing, the estimator below works from the scope you pick.

Tool: [Bath scope & cost builder](https://bathbudget.com/bathroom-remodel/tools/bath-scope-and-cost). Low, typical and high cost for the scope you actually want, with the line items a real quote has.

## Ideas that change surfaces, not plumbing

If the layout works and the room just looks tired, surface ideas go furthest for the money: fresh grout, a reglazed tub, paint suited to a damp room, a new mirror, new hardware.

Most of the looks on inspiration boards live in this group too. A single painted accent wall, or a painted ceiling, gives a small room something to look at. A new floor tile, or the same tile laid in a different pattern, changes the room more than its area suggests, though ask whether the old floor has to come up first, since that adds demolition to the job. Open shelves or a wall cabinet above the toilet add storage without touching a pipe.

**Refinish or re-grout what you have.** Good when: The layout works and the problem is a stained tub, tired grout or a dated vanity. Watch out: A reglaze lasts years, not decades, and it can't fix a leak behind the wall.

Before you cover anything up, look at why it looks tired. If mold keeps coming back in the shower, check the ventilation. The [EPA's guide to mold and moisture](https://www.epa.gov/mold/brief-guide-mold-moisture-and-your-home) says that running a fan or opening a window and cleaning more often will usually stop it recurring. It also recommends keeping indoor humidity below 60 percent, ideally between 30 and 50 percent. Fix the moisture before you regrout.

## Fixture swaps that pay back in water

Swapping a fixture on its existing connections is the middle ground: a visible change with no moved plumbing. These bathroom remodel ideas also keep paying back. EPA's WaterSense label marks fixtures that use less water than standard models:

| Fixture | Standard | WaterSense limit | EPA estimate for the average family |
| --- | --- | --- | --- |
| Showerhead | 2.5 gallons per minute | 2.0 gallons per minute | About 2,700 gallons a year |
| Bathroom faucet | 2.2 gallons per minute | 1.5 gallons per minute | About 700 gallons a year |
| Toilet | 1.6 gallons per flush | 1.28 gallons per flush | Nearly 13,000 gallons a year |

The figures come from the EPA's pages on [showerheads](https://www.epa.gov/watersense/showerheads), [bathroom faucets](https://www.epa.gov/watersense/bathroom-faucets) and [toilets](https://www.epa.gov/watersense/residential-toilets). The toilet is the biggest single change if yours is old: the EPA notes that older, inefficient toilets can use as much as 6 gallons a flush, and puts the saving from WaterSense toilets at more than $170 a year in water costs for the average family. Your own saving depends on your water rates and how your household uses the room.

Lighting fits here too, as long as each new fixture goes where an old one was. Swap the single ceiling light for a brighter one, or replace the bar over the mirror with a fixture that lights your face evenly. Ask whether new lights in new places, such as sconces either side of the mirror or a dimmer on a new switch, need new wiring; if they do, they belong in the layout group.

The exhaust fan is the least glamorous idea on any list and one of the most useful. [ENERGY STAR](https://www.energystar.gov/products/ventilation_fans) says certified ventilation fans use about 48 percent less energy than standard models. Hot, humid air from baths and showers can lead to mold, which is why [ENERGY STAR certified homes](https://www.energystar.gov/newhomes/features-benefits/indoor-air-quality-features) have an exhaust fan in each full bathroom that vents directly to the outdoors. If yours vents into the attic or barely moves air, fix that before the new tile goes up.

## Safety ideas worth building in

A remodel is a good moment to make a bathroom safer, because the walls may be open anyway. The CDC's [study of nonfatal bathroom injuries](https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6022a1.htm) estimated 234,094 injuries among people aged 15 and older treated in US emergency departments in 2008. Falls were the most common cause, at 81.1 percent. Injury rates were highest in or around the tub or shower, and next highest on or near the toilet.

The study's suggestions are plain and inexpensive:

- non-slip strips in the tub or shower;
- grab bars inside and outside the tub or shower;
- a grab bar next to the toilet, if needed.

If the walls are being opened, ask the contractor where grab bars could be anchored later, even if you don't want them yet. For a parent who can no longer step over a tub edge, a walk-in shower is the bigger version of the same idea, and [what a walk-in shower costs](https://bathbudget.com/tub-to-shower/walk-in-shower-cost) compares the two ways to get one.

## Ideas that change the layout

Layout ideas are the ones that move something: the tub becomes a shower, the toilet moves, a wall comes out, a circuit is added. Several popular ideas can land here even though they sound small, so ask the contractor what each one involves: whether a recessed shower niche means opening the wall and redoing its waterproofing, whether heated floors need new wiring under the tile, and whether a double vanity needs a second drain and supply. Ask your local building department whether your job needs a permit before work starts. The [FTC](https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam) lists a contractor asking you to get the required building permits as a warning sign. More in [do you need a permit to remodel a bathroom](https://bathbudget.com/bathroom-remodel/do-i-need-a-permit-to-remodel-a-bathroom).

Replacing a tub with a shower is one layout change you may be weighing, and [the tub-to-shower conversion guide](https://bathbudget.com/tub-to-shower/tub-to-shower-conversion-cost) covers what moves its price. Here are two ways to buy it:

**A one-day liner or wall system.** Good when: You want the tub gone quickly, the substrate behind it is sound, and you'll be in the house a while. Watch out: It goes over what's there. It won't find a leak, and the price is set at your table, not published.

**A conventional remodel with a contractor you choose.** Good when: There's water damage, the layout doesn't work, or you want it done properly once. Watch out: Get three written quotes on the same scope, check the licence, and never pay most of it upfront.

### Lead paint in older homes

If your home was built before 1978, painted walls, trim and doors may contain lead. Under the EPA's [Renovation, Repair and Painting rule](https://www.epa.gov/lead/renovation-repair-and-painting-program-contractors), a firm paid to do work that disturbs paint in a pre-1978 home must be lead-safe certified and follow lead-safe work practices. Minor repair and maintenance that disturbs six square feet or less of paint per room inside is excluded. Demolishing a painted bathroom wall is well past that.

The rule generally doesn't apply to homeowners working on their own home, but the [EPA's page for do-it-yourselfers](https://www.epa.gov/lead/lead-safe-renovations-diyers) still advises hiring a certified lead-safe contractor in a pre-1978 home. Ask any contractor for their certification before demolition starts.

**An idea is not a quote**
A salesperson can turn any of these ideas into a price at your kitchen table. Before you agree to one, get it described and priced in writing by more than one contractor, so you're comparing the same scope.

## Pricing the ideas you pick

Once you have a short list, the [FTC's home improvement advice](https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam) applies to each item on it. Get multiple estimates, each describing the work, the materials, the completion date and the price. Consider only contractors who are licensed and insured, and confirm the license with your state or county. Don't pay the full amount up front: some states limit the down payment a contractor can ask for. Never make the final payment until the work is done and you're satisfied with it.

Quotes for the same idea are often written very differently. [What a bathroom quote should itemise](https://bathbudget.com/bathroom-remodel/what-a-bathroom-quote-should-itemise) lists the lines that make them comparable. If your room is small, [small bathroom remodel cost](https://bathbudget.com/bathroom-remodel/small-bathroom-remodel-cost) explains why the saving is smaller than the floor area suggests.

## Bottom line

The best bathroom remodel ideas fit the scope you actually want. Fix moisture and safety first, swap fixtures on their existing connections where the room works, and save the layout changes for the problems surface work can't solve. Then get each idea priced in writing, on the same scope, from contractors whose license you've checked.

## Common questions

### Which bathroom remodel ideas cost the least?

Start with the ones that leave the plumbing, wiring and walls where they are: regrouting, reglazing a tub, paint, new hardware and swapping fixtures on their existing connections. Ideas that move a drain or a wall add plumbing or framing work, so get those priced separately and in writing.

### Do WaterSense fixtures really save water?

The EPA's figures for the average family: about 2,700 gallons a year from WaterSense showerheads, 700 gallons a year from WaterSense bathroom faucets or aerators, and nearly 13,000 gallons a year from WaterSense toilets.

### Which bathroom remodel ideas need a permit?

Ask your local building department, describing the job you have in mind. The FTC lists a contractor asking you to get the required building permits as a warning sign.

### Does the lead paint rule apply to my bathroom remodel?

If the home was built before 1978 and you pay a contractor to disturb painted surfaces, the firm must be lead-safe certified, unless the work is minor repair disturbing six square feet or less of paint per room inside. Demolition of painted surfaces is covered whatever its size. The rule generally doesn't cover homeowners working on their own home, though the EPA advises hiring a certified contractor.
