Dear Baker Pool & Spa store and hot tub Customer,

As the world battles the Coronavirus, it is essential that we maintain all bodies of water to prevent the spread of other diseases. To that end, it is our sincere hope for our store in the Chesterfield Valley (6 THF Blvd 63005) to remain open during our normal business hours throughout the “Stay at Home Order” issued by the St Louis County Department of Public Health. As a business that supports the sanitation of numerous bodies of water throughout the area, we will continue to serve our customers until otherwise ordered.

That being said, we will not maintain a full staff at the store in an effort to comply with “social distancing” guidelines. We have the following options to serve you during this period:

1. Curbside Pickup – Simply call in your order (636-532-3133) and we will contact you when it is ready.

2. Delivery – We can deliver your season supply of pool chemicals to your garage. Delivery charges are as follows:

  • $25 within 15 miles of our store.
  • $50 from 15 – 30 miles.
  • Beyond 30 miles, please call for a quote.

Water Test Drop Box – Our drop box is located on the outside back wall of the store. You can drop off a water sample 24/7 and we will contact you when your results are ready. Please make sure your bottle includes your name, address and preferred contact number.
For hot tub repair and maintenance services, we are running routs as normal and would ask for your cooperation at this time as follows:

Please remain inside your home when our technician is onsite. The tech will call you when they arrive and before they leave.
We will not be performing any services that require us entering homes at this time.
Thank you for your patience during these unique circumstances.

Since 1968, Baker Pool & Spa has served the St. Louis region providing expertise in the pool and spa industry. Located conveniently in Chesterfield Commons. Stop in and see us today!
