Owners Gene and Rebecca Seabrook, and their interstate business partner Mick Townsend, have been working hard to transform the Worm Bay Road property into a wellness sanctuary by adding a halotherapy room and geothermal spa facility.

Mrs Seabrook said the development started about four years ago, with construction commencing in April last year.

She said works were complete on the "architecturally-designed, luxe" entrance way, as well as the inside unisex change rooms, which included 101 lockers with phone-charging capabilities, a spin dryer for swimwear, and 11 showers with stunning brass-fittings.

"We've also finished our halotherapy room which will be available to book for a 45-minute session," Mrs Seabrook said.

"People can lay back in our arm chairs that recline and breathe in the salt which is really good for respiratory problems, sinuses, eczema and other skin issues, and just overall health."

Mrs Seabrook said the development of the outdoor spa facility was still underway but she hoped it would be up and running in time for National Wellness Week in late September.

She said the facility would include 16 different experiences, including geothermal and nature pools at different temperatures, a foot spa, plunge pool, nourish dome and star gazing.

"Upon arriving, our guests will enter into a unique sanctuary, where we expect them to be able to find their own journey," she said,

"They'll bathe for three to four hours per experience and will enjoy shutting off and really enjoying the benefits of the natural hot springs."

Mrs Seabrook said the facility was licensed to hold up to 200 guests between 7am and 9pm.

"We are still discussing our opening times and maximum capacity (per session) as we want to make it the most comfortable experience possible for our guests," she said.

"We envisage a comfortable experience will be a maximum of 150 people per three to four hour session. Booking in advance will be crucial."

Mrs Seabrook said caves created from artificial rocks would allow the facility to be a year-round destination.

"We want our guests to be able to enjoy this facility at any time of the year which is why we have created a partially enclosed, open-air sanctuary, which will keep Warrnambool's wet and windy elements out during the winter period," she said.

Marshal Judd from Rock 'N' Water landscapes said the rocks were created from scratch over a six week period.

"We weld up a steel armature which is as close to the shape of a rock as we can," he said.

"Then we spray concrete over that steel in a series of layers and the sculptors sculpt every crack and crevice into it. We then do a few different colouring techniques to make them look as real as we can with the moss and the algae."

Mrs Seabrook's husband and business partner Gene said Rock 'N' Water was an interstate business that had been working around the clock to finalise construction.

"Marshal and his family moved here six months ago and have been working six days a week," he said.

"Sometimes Marshal even comes in on a Sunday. He is such an incredible and dedicated creator."

Mr Seabrook also gave a special mention to local contractors Daryl Beechey carpentry, Stephenson's kitchen and joinery, Seabrook fencing and plumber Darren Smith.

"We have had some delays in construction due to inclement weather but we have had great support from our local contractors, the council and the government," he said.

Deep Blue Hotel and Hot Springs was the successful recipient of a $650,000 state government Tourism Demand Driver Infrastructure grant.
