ModWash in Chattanooga: Touchless Wash with In-Bay Detail Options

ModWash is a self-service and automatic car wash facility on Chattanooga's North Shore that combines a touchless tunnel for paint-safe cleaning with open bays for customers who prefer to control their own spray and soap application.

What ModWash actually is

ModWash operates as a hybrid car wash: the main structure houses a fully automatic touchless tunnel where you drive through and cameras trigger soap, rinse, and spot-free water cycles. Adjacent to the tunnel sit four open bays where you insert payment, select soap type and pressure settings, and wash your vehicle by hand. The facility serves owners who want speed and consistency (tunnel) alongside those who trust their own technique or need to target specific spots (bays). It sits in a market where Chattanooga has both traditional hand-wash operators and fully automated alternatives, making ModWash's dual-option approach a practical middle ground.

Services and pricing

The tunnel wash costs $9 for a basic exterior clean and $12 for the premium package, which adds underbody spray and spot-free rinse. Membership is available at $39 monthly for unlimited tunnel washes; members receive a $2 discount per wash beyond the unlimited benefit.

Self-service bay washes run $6 for five minutes of standard soap and water, or $8 for five minutes with premium soap. Additional time purchases are available in $2 and $4 increments. Bay customers can select between foam soap, regular detergent, and high-pressure rinse stages. Pricing is consistent with comparable self-service facilities in the greater Chattanooga area, though ModWash's tunnel option eliminates the labor element entirely, saving time on busy days.

How ModWash compares to other Chattanooga car wash options

Chattanooga has three dominant car wash models: full-service hand washes (attendants wash, dry, and detail), automatic tunnels without bays, and independent self-service bays scattered across the city. ModWash's integration of both touchless tunnel and self-service bays is uncommon locally. Traditional hand-wash operations like those in downtown or Hixson typically charge $20 to $35 for exterior wash and dry, plus additional fees for interior vacuuming or tire cleaning; they require attendance and offer personal attention but have wait times during peak hours. Standalone automatic tunnels without bays are faster but give no control over problem areas like bug splatter or bird droppings. Independent bay clusters demand the same five-to-ten-minute commitment as ModWash but lack the tunnel alternative when you need speed. Choose ModWash's tunnel for weekday lunch breaks or routine weekly maintenance; use the bays if you have visible dirt or want tactile control; go to a full-service hand wash if you need interior vacuuming, tire shine, or undercarriage detail as part of one transaction.

Who ModWash suits and who it doesn't

ModWash works best for owners who wash frequently (weekly or biweekly) and value speed, for those with mild surface dirt who don't need hand drying, and for budget-conscious drivers in the North Shore area. The monthly membership appeals to repeat users. It does not suit owners who need interior vacuuming, tire dressing, or hand-dry services; those customers need a full-service wash. It also does not replace professional detailing for paint protection or deep interior cleaning. Drivers without a North Shore location preference will find equally priced bay options elsewhere in Chattanooga, so proximity matters.

What the first visit involves

Pull into the lot, assess whether you want the tunnel or a bay. For the tunnel, drive to the entrance, select your package on the kiosk (basic or premium), insert a card or phone payment, and proceed into the automated cycle, which takes roughly four minutes. For bays, park in an assigned slot, walk to the control box, select soap type and time, swipe payment, return to your vehicle, and manage the wand. Bays are intuitive for anyone who has used self-service equipment elsewhere. No pre-rinse or post-dry attendants are present at either option.

Hours, parking, and logistics

ModWash is located on North Shore Drive and operates daily from 7 a.m. to 9 p.m. Parking is ample; the facility has dedicated lot space for waiting vehicles and bay access. The North Shore location puts it roughly ten minutes from downtown Chattanooga and five minutes from the riverfront district, making it convenient for commuters heading to or from those areas. Confirm current hours on the facility or by phone, as seasonal adjustments are possible.

ModWash fills a specific need for Chattanooga drivers who prioritize convenience and cost over the frills of hand service, and its dual-option design lets you choose speed or control depending on the day.
