Building a wine cellar costs $40,000 on average, with most homeowners spending $5,000 to $100,000, according to Angi and HomeAdvisor.1,2 Fixr publishes a national average of $33,750 for a defined 75 sq. ft. basement cellar with climate control, finished floors and walls, and an insulated door, inside a $15,000 to $60,000 range.3 All three publishers price the work at $300 to $600 per square foot. Prices below are national averages*.

*National averages, not local quotes. Angi figures are from a guide updated October 2026, HomeAdvisor figures from a guide updated June 2026, and Fixr figures from a guide updated January 2025. Your price depends on cellar size, location in the home, climate control, and finishes.

What the sources say

Source Headline figures Notes
Angi (updated Oct 2026) $40,000 average; most spend $5,000 – $100,000; extremes $3,800 – $125,000; $300 – $600 per sq. ft. Closet/crawl/under-stairs conversion $500 – $2,500; glass cellar $18,000 – $55,000; wine cave from $75,000
HomeAdvisor (updated Jun 2026) Same average, range, extremes, and per-sq.-ft. figures as Angi Corporate sibling of Angi – matching figures alone don’t establish independent corroboration
Fixr (updated Jan 2025) $33,750 average for a defined 75 sq. ft. basement cellar with climate control, finished floors and walls, and an insulated door; range $15,000 – $60,000; low $7,500 (25 sq. ft. wine closet retrofitted from a butler’s pantry); high $180,000 (300 sq. ft. basement cellar with adjacent bar and tasting room) Labor $150 – $300 per sq. ft., stated as at least half of total cost

Angi and HomeAdvisor publish identical headline figures; they are corporate siblings, so matching figures alone don’t establish independent corroboration. Fixr’s figures are separately published, and the pages state no shared sourcing. The headline sets are presented as published, with no conclusion about why they differ.

Cost by location

Fixr prices cellars by location “based on the average size of each location,” while Angi and HomeAdvisor describe conversion costs for existing spaces. The spans differ substantially on some rows and are presented as published, with no conclusion about why they differ.

Location Fixr (2025) Angi/HomeAdvisor (2026)
Wall wine rack $500 – $3,000 $500 – $3,000 (HomeAdvisor)
Under stairs $5,000 – $20,000 $500 – $2,500 total project cost
Crawl space $10,000 – $40,000 $500 – $2,500 including insulation and required modifications
Custom closet / cabinet $15,000 – $60,000 (custom wine cabinet in a closet) $500 – $4,000 (HomeAdvisor custom cabinet, under 10 to 200 bottles); $500 – $2,500 (Angi closet conversion, insulation and custom racks)
Underground / spiral $30,000 – $200,000 Walk-down spiral $30,000 – $200,000; small pull-up spiral cabinet around $1,000
Basement wine cave included in underground range above Fully finished wine cave or basement cellar from $75,000

The wall wine rack and walk-down spiral figures match across publishers (separately published, no shared sourcing stated; the Angi/HomeAdvisor pair are siblings). Angi also prices a glass wine cellar at $18,000 to $55,000 or more, and HomeAdvisor states a glass cellar costs 20 percent more than other materials because of extra-thick insulated glass.1,2

Underground cellar designs (Fixr, 2025)

The ducted-system span matches across the two publishers (separately published, no shared sourcing stated). The wall-unit and split-system spans differ and are presented as published; Fixr labels its figures materials only.

Cost breakdown of an average cellar (Fixr, 2025)

Build area Average costs
Installation $1,700 – $6,000
Climate control $3,000 – $6,000
Building and finishing $6,000 – $30,000
Racks $6,000 – $32,000

Passive vs. active cellars

All three publishers distinguish passive cellars (naturally cool underground spaces) from active cellars (refrigerated, installable anywhere).1,2,3 Fixr states costs for the two fall into roughly the same range, because passive builds require deeper excavation while active builds carry higher climate-control costs. Neither Angi nor HomeAdvisor publishes separate figures for the two types.
