Westlab, the UK’s leading bath salt and mineral wellness brand, has opened a new warehouse and production facility in Knowsley.
The site represents a total investment of over £7.25 million and is expected to create between 40 and 50 new jobs, supporting local employment while strengthening Westlab’s operational capabilities.
The Knowsley site significantly enhances Westlab’s manufacturing and logistics footprint. The facility spans 48,000sq ft and sits on an enclosed site of just over three acres, making it 50% larger than the company’s previous site in Surrey.
At the heart of the warehouse is a state-of-the-art production facility with the ability to produce up to 100,000 units of bath salt per day. This is supported by a large 30,000sq ft storage facility alongside seven unloading bays designed to ensure minimal turnaround times and maintain service levels for major UK and international retailers.
The relocation has increased Westlab’s total output capacity by around 75%, giving the business the scale and agility needed to meet rising consumer demand and support further product innovation.
Sean Daly, CEO at Westlab, said:
“The move to Knowsley represents a significant investment in the North West and a pivotal moment for Westlab. This new facility gives us the manufacturing capacity, efficiency and flexibility we need to scale sustainably, support innovation and ensure consistent availability for our retail partners in the UK and internationally.
It also allows us to create new jobs locally while maintaining the high standards our customers expect from the brand. This is the first move as part of our plans to double the size of the business over the next three years, with the new site playing a central role in supporting long-term growth.”
Leader of Knowsley Council, Councillor Graham Morgan added:
“I’m delighted to welcome Westlab to Knowsley. I’m also delighted that they have chosen to invest here and have created employment opportunities for local people. I know that our Invest Knowsley services have supported Westlab with their move to the borough as have our Knowsley Works team with the recruitment of staff. A great team effort, and I wish Westlab the very best for the future.”

Founded in 2004, Westlab roots began after the discovery of the natural therapeutic power of mineral-rich salts after its founders sought natural remedies to help manage their child’s skin condition.
After experiencing first-hand the benefits of mineral bathing, it sparked a clear and powerful brand mission: to harness the potency and purity of mineral-rich salts to support healthy bodies and minds.
From those humble beginnings, the company has grown into a trusted health & wellness brand stocked by leading retailers across the UK and overseas and claiming the No.1 Bath Salt in the UK accreditation.
