Walk-In Shower or Bathtub: Which Should Your Los Angeles Bathroom Have?

The resale rule first

Real estate agents and appraisers in Los Angeles repeat the same rule: a house should keep at least one bathtub. Families with small children bathe them in a tub, and a house with none loses part of the buyer pool. The rule says nothing about the primary bathroom, where a generous walk-in shower is what most buyers now expect, and where the 1950s and 1960s tub nobody has used in years is the first thing to go. So the usual Valley answer is a walk-in shower in the primary bath and a tub, often a tub-shower combination, in the hall bath.

Walk-in shower vs. bathtub at a glance

What a tub-to-shower conversion really involves

Removing a tub and tiling a shower in its place is the most common bathroom project we do in the Valley, and the parts that matter are the ones you never see. The drain moves from the tub location to the center or a linear drain at the back; on a slab floor that means cutting the concrete. The pan is formed and sloped, a waterproof membrane runs up the walls above the shower head height, the niche and the bench are flashed, the valve and heads are set, and only then does tile go on. The glass comes last. Skip the membrane or slope the pan wrong and the wall behind the tile rots within a few years; that failure is the most common reason we open a bathroom that was "remodeled" a decade ago.

In our 2026 planning tiers the conversion runs $22K–$52K Valley-wide: toward the low end for a standard alcove with a low curb and standard tile, toward the top for a curbless entry on a slab, a linear drain, large-format or slab walls, frameless glass and a second head. The tub-to-shower vs. full remodel guide covers when the whole bathroom should go with it, and the bathroom remodel cost guide shows the tiers by neighborhood.

Curbless showers on Valley slab floors

Most San Fernando Valley houses sit on a concrete slab. A truly curbless shower needs the shower floor to sit lower than the bathroom floor so water runs to the drain and not into the room, which means either recessing the slab (cutting and chipping concrete inside the pan area, then re-pouring the slope) or raising the rest of the bathroom floor. Both are done routinely; both cost more than a 2-inch curb. A low curb with a wide opening gets most of the accessibility benefit at a fraction of the work, and a linear drain along the back wall lets a single slope do the job. On a raised foundation with a wood subfloor the recess is carpentry rather than concrete.

Aging in place

If you plan to stay in the house, the primary bathroom is where that plan lives: a curbless or low-curb shower, a built-in bench, blocking in the walls for grab bars (installed now or later), a handheld head on a slide bar, a comfort-height toilet and a wider door. None of it has to look clinical; it is simply good design now. A walk-in tub is the alternative some owners ask about; it fills and drains slowly and seals wear, and for most people a well-designed shower serves better.

When the bathtub is the right call

• The only bathroom in the house: a tub-shower combination keeps both uses and the buyer pool.
• The kids' or hall bath when the primary bath has or will have the walk-in shower.
• You soak. A deep soaking or freestanding tub in a primary bath big enough for both a tub and a shower is a legitimate luxury, and it sits in the primary renovation tier.
• Resale within a few years in a family neighborhood where every comparable house has a tub.

Permits and timelines

Moving a drain, a valve or a light, or adding a circuit for a heated floor or an exhaust fan, is permitted plumbing and electrical work inspected at rough and final, through LADBS inside the City of Los Angeles or through the city building department in Burbank, Glendale and Beverly Hills. A tub-to-shower conversion takes about 3–4 weeks on site; a primary bath renovation 4–6 weeks once permits are issued; a same-layout refresh with a new tub 3–4 weeks.

How we recommend deciding

Count the bathrooms and the people. One bathroom: a tub-shower. Two or more: a walk-in shower in the primary, a tub in the other, and if you are staying for the long run, build the primary shower curbless or low-curb with the bench and the blocking. Our free on-site estimate checks the slab, the drain location, the framing and the water lines, and ends with one fixed written price for the bathroom you choose.
