Frequently Asked Questions

This Old House's 2026 guide puts most shower door projects at $530 to $1,390, with frameless doors ranging from $1,100 to more than $5,000. A standard frameless single door often lands around $1,000 to $2,500 installed, and a full frameless enclosure costs more. Bay Area labor tends to run above national averages. We give a written price after measuring.

There is no fixed schedule. A well-installed tempered glass door can last for decades; what usually wears out is the hardware, seals, sweeps and rollers, which can often be replaced on their own. Replacement makes sense when the frame is corroded, the glass is etched beyond cleaning, or the door is not safety glass.

There is no single right answer, but there are two main types. Factory-applied coatings such as Guardian ShowerGuard are fused to the glass when it is made and are sold as permanent, while applied coatings such as Diamon-Fusion bond to existing glass and are put on by certified applicators. With Santa Clara's hard well water, either type helps, but a daily squeegee is still the biggest factor.

It is allowed but can feel tight. The Uniform Plumbing Code, which California's Plumbing Code is based on, requires a shower door to leave at least a 22-inch unobstructed opening, and a 24-inch door with hinges and a handle comes close to that. Many people are more comfortable at 26 to 30 inches when space allows, and in a small alcove a narrow fixed panel paired with a wider door often helps.

The city's water quality report lists Santa Clara's well water at 220 to 300 mg/L of hardness, and wells supplied about 59 percent of the city's water in 2020. When that water dries on glass, it leaves calcium and magnesium behind. Squeegeeing after each shower, a protective coating and good ventilation keep spotting down.

It depends on what else is changing. The City of Santa Clara's 2026 fee schedule lists a permit for a like-for-like bathroom remodel, and moving plumbing or rebuilding the shower adds to the scope. Before any larger project, check with the Santa Clara Permit Center at 408-615-2420. Either way, the glass must be tempered safety glass.

Frameless glass is generally easier because there are no metal channels along the bottom and sides where water, soap and minerals collect. Framed and many sliding doors have tracks that need regular scrubbing. With hard water, fewer edges means less buildup.

Published guides put a standard single frameless door at roughly $1,000 to $2,500 installed, and This Old House lists frameless doors in general at $1,100 to more than $5,000. A door with a fixed panel or a full enclosure costs more. We give a written price after measuring.

Both are common. 3/8-inch glass is the usual choice for standard doors and costs less; 1/2-inch glass feels heavier and suits wide doors and large panels. Your hinges must be rated for the weight either way.

Custom glass is made after final measurements, so there is a wait between the measure and the install while the glass is cut and tempered. Installation itself usually takes a few hours. We give you the expected timeline with your quote.

Usually, yes. We check the tile and wall for solid anchoring and measure for any lean or slope. If the wall cannot hold a heavy hinge in the right spot, we can often change the layout so the door hangs on a fixed panel instead.

A little water can escape through the small gaps around the door if the shower head points straight at them. Clear seals, a bottom sweep and smart placement keep that to a minimum.

Frameless doors use thick glass with only hinges and clamps. Semi-frameless doors use thinner glass and add a slim metal frame around the outer edges of the opening, which costs less and handles uneven walls easily.

Generally, yes. Published ranges for semi-frameless run roughly $480 to $1,550, while frameless doors often start around $1,000 installed and go higher. Size and finish move both numbers.

The framed wall channels give a tight edge on the sides, which can help. The door edge still needs good seals and a sweep at the bottom.

Yes. Semi-frameless sliding and hinged doors are made for tub openings, with a bottom track or a sealed threshold depending on the style.

Older framed sliders with heavy aluminum tracks can look dated, but frameless sliders with exposed rollers and a header bar are a current, popular style. They suit small bathrooms where a swing door will not fit.

Worn or cracked rollers, a bent track or mineral buildup in the channel are the usual causes. New rollers and a cleaned or replaced track often fix it without a new door.

Published ranges run from about $400 to $2,050 installed, depending on whether it is framed, semi-frameless or frameless. We give a written price after seeing the opening.

Yes, but the walk-through opening will be under half the width because the panels overlap. We will show you the actual opening size before you decide.

Not always. A fixed panel can be enough if the shower is deep enough and the floor drains well. Shallow showers usually need a door or a second panel to keep spray in.

Published ranges run from about $1,400 for a door and one panel to $5,000 or more for custom multi-panel enclosures. Layout, glass thickness and coatings drive the price.

After. Final measurements are taken on finished tile because tempered glass cannot be cut afterward. It helps to plan the glass before tiling, though, so backing and curbs are in the right places.

It can be. A neo-angle fits a corner and leaves more floor space than a square shower of similar size, though the door is usually narrower.

Glass keeps water in better, does not get moldy at the bottom like a curtain liner, and makes a small bathroom feel larger. Curtains cost less and leave the tub fully open, which some families prefer.

Yes. Frameless sliders and fixed screens are made for tubs. The tub ledge must be checked for level so the glass seals properly.

Published ranges are about $400 to $2,050 depending on style, with HomeServe listing typical glass tub doors at $877 to $1,203. We price after measuring the tub.

A sliding door can limit reach. A fixed screen or a slider that opens to the middle usually works better for bath time.

Usually. Most leaks come from a worn sweep or side seal, or a door that has sagged out of line. New seals and a hinge adjustment fix most of them.

Homeyou's 2026 guide lists most single repairs between about $88 and $489, with a California range of $183 to $468. We quote the specific repair in writing.

No. Tempered glass cannot be reworked, and an edge chip weakens the whole panel. The panel should be replaced, and the door should not be used until it is.

Recent spotting usually cleans off. Spots left for a long time can etch the glass so it stays cloudy, and etching cannot be fully reversed. Coated replacement glass resists it better.

Look for a small permanent mark etched or printed in a corner of the glass. If you cannot find one, have it checked; replacing it with tempered glass is the safe choice.
