How much does it cost to have an interior designer do one room?

A single-room interior design project typically runs $2,500–$12,000 in design fees alone (excluding furniture and materials). Living rooms and primary bedrooms trend toward the higher end because of complexity and procurement volume; a powder room or guest bedroom can fall in the $1,500–$4,000 range for design services.

Which room is most expensive to have an interior designer redesign?

Kitchens are typically the most expensive room to redesign with an interior designer, often running $8,000–$25,000+ in design fees when cabinetry specification, appliance selection, and contractor coordination are included. Open-concept living/dining combinations come second due to cohesion challenges.

Does an interior designer charge separately for each room?

It depends on the fee structure. Flat-fee and percentage-of-project designers usually quote a whole-home fee. Hourly designers bill per actual time, so rooms accumulate separately. Some designers offer per-room packages as a middle ground — typically $3,500–$8,000 per room all-in.

Can I hire a designer for just one room?

Yes. Many designers take single-room projects, especially for living rooms, primary bedrooms, or home offices. Some require a minimum fee ($2,000–$5,000) to make the engagement worthwhile. E-design services often have lower minimums ($500–$1,500) for a single-room digital plan.

Interior Designer Cost Per Room in 2026: What Each Space Really Runs

April 25, 2026

Why Room Type Drives Design Cost

Interior design fees aren't just a function of square footage. They reflect complexity: the number of decisions to make, the volume of materials to specify, the number of contractor trades involved, and how many rounds of revisions the design requires. A 400 sq ft living room demands more design hours than a 150 sq ft bedroom simply because there are more moving parts — seating arrangements, lighting layers, area rugs, window treatments, built-ins, and art placement, all of which need to work together.

Below are realistic 2026 cost ranges for each common room type, broken into design fees (what you pay the designer) and total project costs (design + materials + furniture + labor).

Living Room: $4,000–$15,000 in Design Fees

The living room is most designers' primary battleground. It sets the tone for the entire home. Expect to spend $4,000–$9,000 in design fees for a moderately sized living room refresh (new furniture plan, textiles, lighting, accessories). A full renovation with built-in cabinetry, new flooring, and custom upholstery can push design fees to $10,000–$15,000.

Total project cost (design + all furnishings and materials) typically lands between $18,000 and $65,000 depending on furniture quality. Custom sofas from American or European makers run $5,000–$18,000 alone.

Kitchen: $6,000–$25,000 in Design Fees

Kitchen redesigns are the most complex residential projects a designer handles. Cabinetry specification alone involves dozens of decisions — door profiles, hardware, interior fittings, drawer depths, pull-out mechanisms. Add appliance selection, countertop material, backsplash, lighting, and plumbing fixtures, and you're looking at 60–120 hours of design time.

Design fees for a full kitchen redesign run $6,000–$12,000 for a standard kitchen; kitchens with islands, custom cabinetry, or high-end appliance packages can reach $15,000–$25,000 in design and project management alone. Total renovation costs (including contractor labor and materials) average $50,000–$150,000+ for a quality full gut.

Semi-custom kitchen design consultation: $2,500–$6,000
Full custom kitchen design: $8,000–$20,000
Kitchen + adjacent dining room: $12,000–$28,000

Primary Bedroom: $3,500–$12,000 in Design Fees

Primary bedrooms command significant investment because clients expect them to feel genuinely restorative — not just functional. Upholstered headboards, layered bedding, custom window treatments, lighting, and an integrated closet plan all fall within the bedroom scope.

Design fees average $3,500–$7,000 for a primary bedroom redesign. If the project includes a walk-in closet system specification and an en-suite bathroom, expect $8,000–$12,000 in combined design fees. Total project costs typically land at $12,000–$40,000 depending on bed frame quality and textile investment.

Bathroom: $2,500–$10,000 in Design Fees

Bathrooms are deceptively complex. Every square inch is a decision — tile patterns, fixture finishes, vanity style, mirror size, lighting above vs. beside the mirror, towel bar placement, grout color. A full primary bathroom redesign typically requires 30–60 designer hours.

Design fees run $2,500–$6,000 for a standard primary bath. A spa-style bathroom with custom tile work, heated floors, and freestanding tub can push design fees to $7,000–$10,000. Total renovation costs: $20,000–$80,000 depending on scope and fixture quality.

Powder rooms are smaller but still need careful attention; design fees typically run $1,500–$3,500 for a powder room update.

Home Office: $2,000–$7,000 in Design Fees

Post-2022, home office design has become a core service for most residential designers. Clients want spaces that look polished on video calls, support long work sessions ergonomically, and separate work from home life visually. Design fees average $2,000–$5,000. Built-in desk and shelving specification can push fees higher. Total project costs typically run $6,000–$25,000 depending on whether built-ins are included.

Dining Room: $2,500–$8,000 in Design Fees

Dining rooms involve fewer decisions than living rooms but are unforgiving about scale — the table size relative to the room, chandelier hang height, chair seat height relative to table apron, and rug dimensions must all be exact. Design fees for a dining room project run $2,500–$5,000 for a standalone space; combined with a living room, expect a package discount to bring the combined fee to $7,000–$12,000.

How to Stretch Your Per-Room Budget

Phase the project: Do the furniture plan first, wait 60 days, then add custom textiles and window treatments. Spreading procurement across months smooths cash flow.
Consider e-design: Online interior design services like Havenly, Decorist, or boutique e-design designers charge $300–$1,500 per room for digital plans you execute yourself. Quality varies, but for lower-budget rooms it's a genuine option.
Focus on bones, not accessories: Invest design hours in furniture scale, lighting placement, and color selection. Accessories can be self-sourced over time without designer guidance.
