Bathroom Remodel Cost by Size: Powder Room to Master Bath in Aurora CO

Updated April 2026 · 12 min read · By the Tilers4you team, Aurora CO

The most common question we get before an estimate is “what should I expect to pay?” The honest answer is: it depends heavily on room size, scope, and material choices. After fifteen years installing tile in Aurora and across the Denver metro, here are the real numbers from projects we’ve completed in 2025–2026.

Powder Room (approximately 20 sq ft)

The powder room is a half bath — toilet and sink only, no shower or tub. It’s the most affordable remodel by scope, but costs can climb fast if you start moving plumbing or specifying custom finishes.

A standard powder room remodel runs 3–5 working days. That’s demo, new tile floor (20–30 sq ft of tile), vanity swap, toilet replacement, lighting update, paint, and hardware. Labor typically represents about 40% of the total cost.

What pushes a powder room toward $9,000: moving a drain or supply line, adding a tile feature wall, specifying a custom furniture-style vanity, or selecting premium fixtures. Moving plumbing in a powder room on a slab foundation is a serious cost driver — sometimes $1,500–3,000 just for the plumbing relocation alone.

Hall Bathroom (approximately 40 sq ft)

The hall bath is a full bath with a tub/shower combo — the standard configuration in most Aurora homes built between 1970 and 2005. It sees heavy daily use, which means waterproofing quality matters more here than anywhere else in the house. This is not the place to hire the cheapest bidder.

A hall bath remodel runs 8–14 working days, accounting for mandatory waterproofing and thinset cure times. Converting a tub/shower combo to a dedicated walk-in shower adds $2,000–$4,000 to the project cost (additional substrate work, new drain, larger tile area) and typically extends the schedule by 2–4 days.

• •
  Keeps cost down: maintaining the existing plumbing layout, ceramic tile on inside shower walls, standard fixture sizes that don’t require custom cuts.
• •
  Pushes cost up: shower conversion, heated floor, moving the vanity location, large-format tile (12×24 or larger) requiring additional floor prep for flatness.

Primary Bathroom (approximately 80 sq ft)

The primary bath is where Aurora homeowners typically invest the most — and where they also have the most decisions to make. Walk-in shower, freestanding or built-in tub, double vanity, heated floor: the scope combinations are wide and so are the price ranges.

Timeline for a primary bath is 18–28 working days. That accounts for the larger tile area, more complex layout decisions, heated floor mat installation (done before tile, requires its own cure cycle), and the additional plumbing and electrical work a primary bath typically involves.

What drives primary bath costs toward $45,000 and beyond: steam shower systems (generator, vapor-tight enclosure, specialized tile setting requirements), custom bench with waterproofed substrate, two separate shower niches, large-format 24×48 tile that requires a laser-flat floor prep, and designer fixtures where a single thermostatic valve assembly can run $1,200–$2,500 before installation.

Luxury Master Bath (120+ sq ft)

At this scale, the bathroom is a destination rather than a utility space. We see these projects most often in newer Tallyn’s Reach and Saddle Rock homes in Aurora that were built with large footprints but builder-grade finishes. Homeowners who have owned for 10+ years frequently invest here.

At this price point, the tile labor alone can run $12,000–$18,000. Timeline is 30–45+ working days. Projects of this scope almost always require an Aurora building permit, a plumbing inspection, and an electrical inspection — factor in 1–3 weeks for permit turnaround before demo can start.

What’s Inside the Price: A Cost Breakdown

For a mid-range primary bath ($28,000 total project), here is approximately where the money goes:

Where to Save Money

Smart Cost Reductions

• •
  Keep plumbing in place. Moving a drain is the single biggest cost driver in any bathroom remodel. If you can live with the existing toilet, vanity, and shower locations, you can save $1,500–$4,000 depending on the scope of the move.
• •
  Ceramic tile in low-visibility areas. The inside walls of a shower stall (as opposed to the feature wall visible from the bathroom) can use ceramic tile at $1.50–$2.50/sq ft material cost without compromising aesthetics.
• •
  Standard fixture footprints. Non-standard dimensions require more custom cuts. A 60-inch standard tub cutout is much cheaper to tile around than a freeform tub on a platform.
• •
  Semi-custom vs. custom vanity. A well-made semi-custom vanity from a quality supplier at $600–$1,200 looks nearly identical to a $3,500 custom piece in a finished bathroom. Put the savings into tile.
• •
  Simple tile layout patterns. Straight lay and running bond are significantly faster to install than herringbone or diagonal. With tile labor at $4.50–$7.00/sq ft, a complex pattern on 80 sq ft adds real money.

Where Not to Save Money

These are the areas where cutting cost produces failures that cost far more to repair than you saved.

• •
  Waterproofing membrane. Full stop. A proper waterproofing system — RedGard, Schluter Kerdi, Wedi board, or similar — is what keeps water in the shower and out of your subfloor and framing. A contractor who says “we use plastic sheeting” or skips membrane entirely is setting you up for mold, rot, and a complete tear-out within 3–7 years. This repair costs $15,000–$30,000 when structural damage is involved.
• •
  Cement board or foam board substrate. Paper-faced drywall (including “moisture-resistant” greenboard) is not an appropriate backer in wet areas. Cement board and foam board products (Wedi, Schluter, USG Durock) are the correct substrates. If a bid doesn’t include CBU or foam board in the shower, ask why.
• •
  Skilled tile labor. A $2.00/sq ft cheaper installer who rushes the work, skips cure times, or uses inadequate thinset coverage costs you $10,000+ when the tile needs to come out. Tile labor is not a commodity. References and portfolio matter.
• •
  Exhaust ventilation. Aurora’s climate — cold winters, low relative humidity — means hot showers create significant condensation. An undersized or non-functional exhaust fan is a direct path to mold on ceiling grout and painted surfaces. Size the fan for the room (CFM = room volume ÷ 7, minimum).

How to Read a Bid

When comparing estimates, look beyond the bottom line. The difference between a $13,000 bid and a $16,000 bid on the same hall bath often comes down to what the cheaper bid has omitted:

• •
  Does the bid include a waterproofing membrane by name? (It should specify RedGard, Kerdi, Wedi, or similar — not just “waterproofing”)
• •
  Does it include cement board or foam board as shower wall backer?
• •
  Does it include permit fees, or are those extra?
• •
  Is tile included in the bid, or materials-only with tile supplied separately?
• •
  Is demo and haul-off included?
• •
  Is the contractor licensed with the state of Colorado and carrying general liability + workers’ compensation?

A lower bid that excludes waterproofing, substrate, or permits is not a lower-cost project. It is a more expensive project that hides the true cost until you get the final invoice — or until you have a water damage claim three years later.
