SplashZen Bath Splash Guard Update | Shark Tank Season 15

Every time Rodney and Tanya Rasmussen bathed their kids, water went everywhere and messed up the bathroom. So they made SplashZen, a splash guard that sticks to the side of the tub and blocks the water from splashing out. It keeps the bathroom dry and makes bath time easier for parents and pet owners. Will any of the sharks make an offer? Let’s find out in our SplashZen update and pitch recap.

If you’re short on time, here’s a quick overview of what happened to SplashZen after Shark Tank.

Rodney and Tanya entered Shark Tank Season 15, seeking $100,000 for 10% equity in their bath-time accessory. After their pitch, they left with a deal from Barbara Corcoran for $100,000 in exchange for 14% equity.

In terms of a SplashZen update, the company focused on direct online sales and small-batch production following its Shark Tank appearance, with the splash guard frequently selling out and receiving strong customer feedback.

Shark Tank SplashZen Pitch

• Entrepreneurs: Rodney and Tanya Rasmussen
• Business: Bath splash-guard
• Ask: $100,000 for 10% equity
• Result: $100,000 for 14% equity, plus a $100,000 line of credit
• Shark: Barbara Corcoran

Busy parents, Rodney and Tanya, dreaded bath time with their three boys. Water always ended up on the floor, and cleaning up after the mess turned a fun routine into a stressful chore.

However, that all changed when they created a bathtub splash guard called SplashZen.

The SplashZen is designed to keep the water inside the tub, no matter how wild the splashing gets.

The product works like a retractable window shade. It attaches to one side of the tub and stretches across, sealing along the bottom with a suction strip.

This keeps the water contained and lets kids play longer without parents worrying about soaked floors.

As a bonus, Rodney added that SplashZen also works for pet baths. That means families with dogs get a two-in-one solution.

When they handed out samples, the sharks were impressed. Lori Greiner immediately noted that it was well-made, sturdy, and smart.

Tanya explained that SplashZen is a one-time purchase built to last for years. It costs them $40 to produce and sells for $99 at retail.

So far, all their sales have come from direct-to-consumer channels, mainly TikTok and other social media platforms.

They’ve sold $80,000 worth of product to date. $10,000 of that came in the last quarter of the previous year, with the rest coming in during the year of filming.

Kevin O’Leary raised concerns over branding. He felt it would be too hard to explain at retail, especially sitting on a shelf without a demo.

Rodney agreed. That, he said, was exactly why they needed a shark to help with branding, messaging, and retail strategy.

However, not every shark saw the same potential. Robert Herjavec went out first.

He said he didn’t see the need for the product and simply wipes up water after his twins’ baths.

Mark Cuban followed, saying SplashZen felt like a nice-to-have, not a must-have.

Kevin stood by his earlier concern and also went out, saying it was hard to sell in retail without a demo.

That left Lori and Barbara Corcoran still in.

Lori offered $100,000 for 20% equity. She said she invests in people and believed the couple had the drive to succeed.

Barbara then undercut her with an offer of $100,000 for 15%, plus a $100,000 line of credit. She pointed to her past success helping brands lower costs and improve packaging.

Rodney asked if the two sharks would consider teaming up. Lori declined and emphasized her experience with over 1,000 products and global manufacturing.

Still interested, Rodney asked if Lori would match Barbara’s offer. Lori agreed to $100,000 for 17.5% equity plus the same $100,000 line of credit.

As the couple discussed their options, Barbara dropped her equity ask to 14.5%. Rodney pushed one last time, asking if she’d go down to an even 14% equity, and she agreed.

In the end, the couple accepted Barbara’s deal. Lori wished them the best and said she genuinely wanted them to succeed.

Shark Tank SplashZen Update

According to our SplashZen update, we found that there is no official confirmation whether the deal with Barbara Corcoran closed or not.

However, following the episode, which aired in early 2024, SplashZen saw a noticeable surge in traffic and product demand.

Their website and social media gained traction, thanks to the exposure and earlier viral TikTok content.

Despite this momentum, the product never made its way into big-box stores or major retail chains.

As of mid-2025, SplashZen remained exclusively available through its website.

Unfortunately, SplashZen is shutting down pretty soon.

In a heartfelt Instagram reel shared in June 2025, Tanya alluded to recent U.S. tariffs on Chinese imports as one of the key reasons behind their decision to shut down the company.

However, the website will stay up until their current stock runs out, before they officially shut everything down, Tanya said.

At the time of this writing, the Rasmussens have not announced any plans to relaunch or start a new venture.

As a result, this marks the end of our SplashZen update. Unless, of course, new information comes up and we need to circle back.

We’ll be keeping an eye on what happens next. In the meantime, you can get your SplashZen on their website.
