When Jamie Lenore McKillop and her husband moved to Venice Beach at the end of 2019, the couple felt as if they had secured their Los Angeles dream home.

The 3,000-square-foot property straddles the line between midcentury-modern and modernist, a rarity at a time when the area’s newly developed houses look more or less the same.

Ms. McKillop was adamant about keeping the original features, but the bathroom felt noticeably out of place compared with the rest of the house. Every other room had its own personality: the kitchen pistachio green with a cherry red hidden bar cabinet; a bedroom in butter yellow; and the exposed stairs in the ceiling above the kitchen sink where her cat perches and plays peek-a-boo.

“I wanted to find a way to keep the integrity and the character, but do something that felt more current, but also a bit more of a statement,” she said.

During the three-month renovation, Ms. McKillop became obsessed with International Klein Blue, the dynamic pigment created by the French artist Yves Klein in 1961. In addition to being the new backdrop for her bathroom tiles, this specific shade has become an integral part of the identity for Lazy Jamie, a home décor brand Ms. McKillop founded in 2023. She sells a variety of stainless steel home wares, the latest being a portable TV tray table with a mirror chrome tubular steel base and high-gloss wood top in her signature color.

“Yves Klein said that blue was limitless,” Ms. McKillop said. “I want to challenge how people experience rest through furniture, so the definition of blue acting as a kind of freedom and as an antidote to restrictive limits really resonates with me. I hope to subvert the idea of laziness to be positive.”

So while Gen Z is busy bed rotting, Ms. McKillop, 33, prefers losing track of time in the bathroom.

“The bathroom is my favorite because I can lock the door and don’t have to worry about anyone coming in,” she said. “It’s not just a bathroom; it’s a dressing room, a makeshift spa, and sometimes an office. It’s my retreat.”

Ms. McKillop shared a few essential pieces that have elevated her bathroom experience.

5-9 TV Tray Table, $546 at Lazy Jamie

A TV tray, Ms. McKillop said, can be an “unexpected furniture piece for your most in-between moment,” whether that takes place in the living room, bedroom or bathroom.

“It’s this moment of joy that none of us really talk about, but we all share,” she said. “It feels so good, when my partner’s out of town, or when I’m alone, and that’s what I’m doing — I’m not eating in silence at a dining table.”

Inspired by her grandmother and the trays around her house, Ms. McKillop reimagined a version with this generation in mind. Unsurprisingly, she wanted to “bring in the blue in a really prominent way,” so the removable butler tray is powder-coated in International Klein Blue or off-white for fans of neutral palettes.

She emphasized that the table was designed for solo activities in smaller spaces rather than as part of a set for an entire household. The designer uses it in a variety of ways, including as a desk while working from her bed, a platform for watching movies in the bathtub, or “an ultra chic tampon holder” next to the toilet, she said.

“When I was in my 20s and had roommates we would eat in front of the TV, we wouldn’t sit at the dining table,” she said. “More of us than ever are living in small spaces and eating in front of the TV because oftentimes we’re ordering takeout and watching Netflix. Our culture is much more set up for that moment than they are the Norman Rockwell idea of eating dinner.”

While many of the fixtures desperately needed to be replaced, Ms. McKillop insisted that the driving force behind the bathroom renovation was color not cosmetics. Since the original tiles, which were a “very ’90s blue,” needed to be ripped out regardless, Ms. McKillop thought it would be fun to update them with a hue that felt more current. While searching for International Klein Blue ceramic subway tiles online, she was led to the G22 Opal Blue Tile from Heath Ceramics, which has stores in California and Texas.

“Now that I feel like I’ve become more entrenched in this Yves Klein Blue world, I’ve researched more about the blue, why people are drawn to it and his beliefs around it,” she said. “It’s hard to define, but it’s sort of this ultramarine. He has said that it has no dimensions, it’s kind of limitless and it represents freedom — that’s why when you look at it, it has that calming, relaxing quality.”

Ms. McKillop is so fond of the tiles that she has a matching ceramic mug and bowl for a pleasing “pop of blue” on her table, too.

A good vanity is hard to find these days, so Ms. McKillop was willing to do whatever was necessary in order to preserve the original piece in her bathroom. She sanded down and polished the stone countertop, and then upgraded the outdated fixtures with ones from Dornbracht. Her followers on TikTok and Instagram continue to leave comments saying how beautiful the contrast is between the orange-tinted rosewood and deep blue tiles.

“When you have the sunlight coming in, it definitely creates more of that contrast and it really pops,” she said. “Unfortunately, because it’s vintage at this point, it is one of a kind. You can’t buy it, but someone should make it.”
