If you're planning a bathroom remodel or a whole-home refresh in the Chicago area, you've probably wondered whether hiring an interior designer is worth the investment — and what it actually costs. At Century City Baths, we work alongside designers on projects throughout Chicagoland every week, and we've seen firsthand how the right design partnership can transform a renovation. We've also seen homeowners get blindsided by fees they didn't expect.
Here's an honest, up-to-date breakdown of what interior designers charge in 2027, how the different pricing models work, and when it makes sense to bring one onto your project.
The Short Answer
In 2027, most interior designers charge $100 to $200 per hour, with high-end and award-winning designers commanding $300 to $500 per hour or more. Flat-fee projects typically range from $2,000 to $12,000, though full-home designs in neighborhoods like Lincoln Park, Winnetka, or Hinsdale can climb well past that.
For a single bathroom, you can generally expect design fees somewhere in the $2,000 to $6,000 range depending on the scope, the designer's experience, and how much of the project they manage.
The Five Ways Interior Designers Charge
Not every designer bills the same way. Understanding these models before your first consultation will save you a lot of confusion later.
1. Hourly Rate
Typical range: $100–$200/hour (up to $500/hour for top-tier designers)
This is the most common structure for smaller projects or consultation-only work. You pay for the time the designer spends on your project — meetings, sourcing, drawings, site visits, and vendor coordination.
Hourly makes sense when:
- You only need help with a few decisions
- You want a second opinion on a layout or material selection
- Your project is small in scope, like a powder room refresh
The downside is unpredictability. Without a cap, hours add up fast. Always ask for an estimated total and request that the designer notify you before exceeding it.
2. Flat Fee (Fixed Fee)
Typical range: $2,000–$12,000+
A flat fee covers the entire design scope for one agreed-upon price. The designer evaluates your project, estimates their hours, and quotes a single number.
This is the most popular model for defined projects like bathroom remodels because everyone knows the cost up front. For a primary bathroom renovation in Chicagoland, a flat design fee of $3,000 to $7,000 is common. A full first-floor redesign might run $8,000 to $15,000.
Just be clear on what's included. Does the fee cover construction drawings? Project management during the build? Revisions? Shopping trips? Get it in writing.
3. Cost Per Square Foot
Typical range: $5–$20 per square foot
Used more often on new construction and large-scale renovations, this model scales the fee with the size of the space. A 1,500-square-foot renovation at $12 per square foot would run $18,000 in design fees.
Square-footage pricing is less common for bathrooms simply because the rooms are small but design-intensive — a 60-square-foot bathroom requires nearly as much planning as a 300-square-foot bedroom, but would generate a fraction of the fee.
4. Cost-Plus (Markup on Purchases)
Typical markup: 10%–40% over wholesale
With cost-plus, the designer buys furniture, fixtures, tile, and materials at trade pricing and sells them to you with a markup. Many designers use this in combination with a reduced hourly rate or flat fee.
The upside: designers have access to trade-only lines and wholesale pricing you can't get on your own. Sometimes the trade discount offsets much of the markup. The downside: it can be hard to tell what you're actually paying for the product versus the service.
Ask your designer directly whether they're passing along trade discounts and what their markup percentage is.
5. Percentage of Total Project Cost
Typical range: 10%–25% of the project budget
Here the design fee is a percentage of what you spend on construction, materials, and furnishings. On a $60,000 bathroom remodel, a 15% design fee would be $9,000.
This model is common for large renovations and whole-home projects. The obvious concern is the built-in incentive to increase the budget — so make sure you set a firm project cap before signing.
What Drives the Price Up or Down
Several factors influence where you land in those ranges:
Experience and reputation. A designer with 20 years of published work charges more than someone three years into their career. Both can do excellent work; you're paying for judgment, vendor relationships, and the ability to anticipate problems.
Project scope. A consultation on tile and paint colors costs a fraction of a full gut renovation with custom millwork and relocated plumbing.
Location. Design fees in downtown Chicago and the North Shore run higher than in the western or southern suburbs.
Level of service. Some designers hand you a plan and step away. Others manage procurement, coordinate with your contractor, oversee installation, and handle the final styling. Full-service costs more because it is more.
Custom work. Custom vanities, built-ins, and bespoke fixtures require detailed drawings, vendor coordination, and more design hours.
Does an Interior Designer Actually Save You Money?
This is the question we get most often, and the honest answer is: sometimes yes, sometimes no — but almost always they save you from expensive mistakes.
Here's what a good designer prevents:
- Ordering the wrong tile quantity or discovering mid-project that a selection is on 14-week backorder
- Layouts that don't work, like a vanity that blocks the door swing or a shower niche in the wrong wall
- Costly change orders caused by decisions made on the fly during construction
- Buying things twice because the first choice didn't fit the space or the overall scheme
On a $50,000 bathroom remodel, a single major change order can cost $3,000 to $8,000. A designer who prevents one of those has essentially paid for themselves.
Designers also often have access to trade pricing on fixtures, tile, and vanities that can offset a meaningful chunk of their fee.
When You Probably Don't Need a Designer
We're not going to tell you every project requires one. You might be fine without a designer if:
- You're doing a straightforward tub-to-shower conversion with standard fixtures
- You have a clear vision and are comfortable making selections
- Your remodeler offers in-house design support (more on that below)
- Your budget is tight and every dollar needs to go toward materials and labor
When a Designer Is Worth Every Dollar
Bring one in when:
- You're moving plumbing, walls, or windows
- The space has awkward dimensions or structural constraints
- You want a cohesive look across multiple rooms
- You're planning to sell and want maximum resale impact
- You're decision-fatigued and need someone to narrow the options
- Your budget is substantial enough that mistakes get expensive fast
The Century City Baths Approach
Here's something a lot of Chicagoland homeowners don't realize: you don't always need to hire a separate interior designer to get professional design input.
At Century City Baths, design guidance is built into our remodeling process. We help you with layout planning, fixture and finish selection, and material coordination as part of your project — not as a separate line item. Our team walks you through tile options, vanity configurations, lighting placement, and storage solutions, and we show you how it all works together before anything gets ordered.
For homeowners who want a dedicated designer for a larger or more design-forward project, we collaborate seamlessly with outside designers. We've worked with designers across Chicago and the surrounding suburbs, and we know how to keep that partnership productive — clear communication, accurate field measurements, and no surprises on the job site.
Either way, you get a bathroom that's planned properly before the first tile is set.
Questions to Ask Before You Hire a Designer
If you decide to bring on an independent designer, ask these before signing anything:
- What's your fee structure, and what exactly does it include?
- Do you charge a markup on products? If so, what percentage?
- How many revision rounds are included?
- Will you coordinate with my contractor, and is that time billable?
- Can I see three projects similar in scope and budget to mine?
- What's your typical timeline from first meeting to final plans?
- Who handles ordering, delivery tracking, and damaged-goods claims?
- Do you carry professional liability insurance?
Get the answers in writing as part of your contract.
Realistic 2027 Budget Snapshot
| Project Type | Typical Design Fee | |---|---| | Single-room consultation | $300 – $1,200 | | Powder room | $1,500 – $3,000 | | Hall or guest bathroom | $2,000 – $4,500 | | Primary bathroom | $3,500 – $8,000 | | Kitchen | $5,000 – $12,000 | | Whole-home design | $12,000 – $40,000+ |
These are Chicagoland-area estimates. Expect the higher end downtown and on the North Shore, and the lower end in outlying suburbs.
The Bottom Line
Interior designer costs in 2027 range from $100 to $500 per hour, $2,000 to $12,000+ for flat-fee projects, or 10% to 25% of your total budget depending on the model. For a Chicagoland bathroom remodel, budget $2,000 to $6,000 if you're hiring independently.
But before you add that line item, find out what design support your remodeler already provides. A bathroom specialist who handles design and construction under one roof eliminates the coordination gaps that cause delays and change orders — and often delivers the same result for less.
